Let's understand together what a magnetic field is. After all, many people live in this field all their lives and do not even think about it. Time to fix it!
A magnetic field
A magnetic field is a special kind of matter. It manifests itself in the action on moving electric charges and bodies that have their own magnetic moment (permanent magnets).
Important: a magnetic field does not act on stationary charges! A magnetic field is also created by moving electric charges, or by a time-varying electric field, or by the magnetic moments of electrons in atoms. That is, any wire through which current flows also becomes a magnet!
A body that has its own magnetic field.
A magnet has poles called north and south. The designations "northern" and "southern" are given only for convenience (as "plus" and "minus" in electricity).
The magnetic field is represented by force magnetic lines. The lines of force are continuous and closed, and their direction always coincides with the direction of the field forces. If metal shavings are scattered around a permanent magnet, the metal particles will show a clear picture of the magnetic field lines emerging from the north and entering the south pole. Graphical characteristic of the magnetic field - lines of force.
Magnetic field characteristics
The main characteristics of the magnetic field are magnetic induction, magnetic flux and magnetic permeability. But let's talk about everything in order.
Immediately, we note that all units of measurement are given in the system SI.
Magnetic induction B - vector physical quantity, which is the main power characteristic of the magnetic field. Denoted by letter B . The unit of measurement of magnetic induction - Tesla (Tl).
Magnetic induction indicates how strong a field is by determining the force with which it acts on a charge. This force is called Lorentz force.
Here q - charge, v - its speed in a magnetic field, B - induction, F is the Lorentz force with which the field acts on the charge.
F- a physical quantity equal to the product of magnetic induction by the area of the contour and the cosine between the induction vector and the normal to the plane of the contour through which the flow passes. Magnetic flux is a scalar characteristic of a magnetic field.
We can say that the magnetic flux characterizes the number of magnetic induction lines penetrating a unit area. The magnetic flux is measured in Weberach (WB).
Magnetic permeability is the coefficient that determines the magnetic properties of the medium. One of the parameters on which the magnetic induction of the field depends is the magnetic permeability.
Our planet has been a huge magnet for several billion years. The induction of the Earth's magnetic field varies depending on the coordinates. At the equator, it is about 3.1 times 10 to the minus fifth power of Tesla. In addition, there are magnetic anomalies, where the value and direction of the field differ significantly from neighboring areas. One of the largest magnetic anomalies on the planet - Kursk and Brazilian magnetic anomaly.
The origin of the Earth's magnetic field is still a mystery to scientists. It is assumed that the source of the field is the liquid metal core of the Earth. The core is moving, which means that the molten iron-nickel alloy is moving, and the movement of charged particles is the electric current that generates the magnetic field. The problem is that this theory geodynamo) does not explain how the field is kept stable.
The earth is a huge magnetic dipole. The magnetic poles do not coincide with the geographic ones, although they are in close proximity. Moreover, the Earth's magnetic poles are moving. Their displacement has been recorded since 1885. For example, over the past hundred years, the magnetic pole in the Southern Hemisphere has shifted by almost 900 kilometers and is now in the Southern Ocean. The pole of the Arctic hemisphere is moving across the Arctic Ocean towards the East Siberian magnetic anomaly, the speed of its movement (according to 2004 data) was about 60 kilometers per year. Now there is an acceleration of the movement of the poles - on average, the speed is growing by 3 kilometers per year.
What is the significance of the Earth's magnetic field for us? First of all, the Earth's magnetic field protects the planet from cosmic rays and the solar wind. Charged particles from deep space do not fall directly to the ground, but are deflected by a giant magnet and move along its lines of force. Thus, all living things are protected from harmful radiation.
During the history of the Earth, there have been several inversions(changes) of magnetic poles. Pole inversion is when they change places. The last time this phenomenon occurred about 800 thousand years ago, and there were more than 400 geomagnetic reversals in the history of the Earth. Some scientists believe that, given the observed acceleration of the movement of the magnetic poles, the next pole reversal should be expected in the next couple of thousand years.
Fortunately, no reversal of poles is expected in our century. So, you can think about the pleasant and enjoy life in the good old constant field of the Earth, having considered the main properties and characteristics of the magnetic field. And so that you can do this, there are our authors, who can be entrusted with some of the educational troubles with confidence in success! Coursework international and national law and other types of work you can order here.
This article is not a revelation of various "masters" and "lords", and the information presented was not obtained through various intricate practices and communication with spirits.
This material is the thoughts of the author. It's just that at a certain moment a rather interesting logical chain of facts and events developed. I apologize in advance for any inaccuracies and possibly gross errors. I would be grateful for criticism, as well as possible additions. I would like to hear the opinion of people in the know.
I want to talk about the Earth's magnetic field. There is plenty of information about it and it all comes down to one thing - the Earth's magnetic field protects our planet from the harmful effects of solar and cosmic destructive energies delivered to us by the solar wind.
The destruction of the magnetic field threatens the death of all life on Earth, etc. etc. Neither more nor less, the death of everything, period.
Is it really? Let's try to figure it out. What is so fatal and destructive can be contained in the solar wind?
Let's not torture ourselves with searches and turn to Wikipedia:
The solar wind is a stream of ionized particles (mainly helium-hydrogen plasma) flowing from the solar corona at a speed of 300-1200 km/s into the surrounding space. It is one of the main components of the interplanetary medium.
Many natural phenomena are associated with the solar wind, including space weather phenomena such as magnetic storms and auroras.
In relation to other stars, the term stellar wind is used, so that in relation to the solar wind one can say "stellar wind of the Sun."
The concepts of "solar wind" (a stream of ionized particles) and "sunlight" (a stream of photons) should not be confused. In particular, it is the effect of sunlight pressure (and not wind) that is used in the projects of the so-called solar sails.
Due to the high conductivity of the solar wind plasma, the magnetic field of the Sun is frozen into the outflowing wind currents and is observed in the interplanetary medium in the form of an interplanetary magnetic field.
The solar wind forms the boundary of the heliosphere, which prevents the penetration of interstellar gas into the solar system. The magnetic field of the solar wind significantly weakens the galactic cosmic rays coming from outside.
The solar wind generates on the planets of the solar system that have a magnetic field, such phenomena as the magnetosphere, aurora and radiation belts of the planets.
And it is from this stream of ionized particles that the magnetic field saves us.
It is known about the magnetic field that it is not constant and its strength changes. It seems that even a cycle of its maximum and minimum strength of 4000 years has been established. You can also find information that the magnetic field is closely related to the Earth's ionosphere. It is also known that the magnetic and electromagnetic fields are close in nature.
This is where the doubts came in. Does the solar wind really bring deadly particles with it? Or maybe vice versa? Maybe the particles that the Sun shares with us are not at all destructive, and it is in them that the energy we need is contained. Is the Earth's magnetic field an artificial shield created (or reinforced - more on that below) in order to block this energy.
Our ancestors called the sun Dazhdbog. Is it really only because the Sun gave them warmth and light that people worshiped and idolized him? Maybe the Sun gave something else? Maybe it was something that was the energy that was delivered to us by the solar wind?
Today there is a lot of talk about climate weapons. We are all well aware of the American HAARP installations installed in several places. Allegedly, with their help, through the impact on the Earth's ionosphere, the Americans manage to influence the weather.
The ionosphere is directly related to the Earth's magnetic field. I think talking about climate weapons is dust in the eyes. The real task of HAAPR installations is to increase the Earth's magnetic field!
For the same purpose, another monster was built - the hadron collider, which is essentially a giant electromagnet. The whole world is crammed with electrical appliances, surrounded by high-voltage wires and riddled through with waves of various nature. What are the subways alone in the megacities of the entire planet - these are huge emitters of electromagnetic waves. By the way, the announced unprecedented construction of the subway in Moscow may be connected precisely with this.
As we know, during the moments of the so-called magnetic storms, electronics fail, as well as weather-dependent people experience health problems. We are told that this is due to perturbations in the Sun. But is it? As you know, both the USSR and the USA investigated the energy of the solar wind by launching devices into space, and successfully investigated. These devices were sent directly into the flow of solar and wind and did not break anything, successfully completed the task and sent data to Earth. But the electromagnetic field, here I think physicists will agree with me, can easily disrupt the operation of electrical appliances.
Do not the comrades who control the world use the above-mentioned amplifiers in order to increase the protective force of the Earth's magnetic field at the right moment at the time of the release of solar energy?
It is quite possible that the disruption of satellites, the deterioration of health and the failure of transformers, computers and other devices is the result of these manipulations.
Perhaps these manipulators are able to control the magnetic field, but they do it only in “one direction” - in the direction of increasing its strength. It does not fit into one's head that, having the opportunity to reduce this field, they would not use it for the purpose of allowing "disastrous" solar energy to any of the "uncomfortable countries". This is what gives reason to believe that the energy coming from the solar wind is not destructive, but divine in nature, and its penetration to the Earth poses a direct threat to the world rulers and does not fit into their plans. For them, this is fraught not only with a loss of power, but with a loss of life, a complete exit of the situation from control.
In turn, I came across information about the change of poles and the possible disappearance of the Earth's magnetic field for several days. It was said that people could go crazy from it. It is quite possible that the energy of the sun will bring people the truth, which not everyone can perceive. Isn't this a deliberate stuffing, in order to declare anyone who receives a dose of this energy crazy and dangerous to society and subject to liquidation, not in vain in the USA coffins stocked up))))
Now the works of Nikola Tesla are very popular. Various coils, generators, transformers. Here I can be mistaken and once again I apologize. If electricity is capable of creating an electromagnetic field, then electricity can be obtained from an electromagnetic field. Tesla found a way to draw energy from the Earth's magnetic field. This frightened the manipulators, they brainwashed him and Tesla destroyed his developments, because he was sure that if the Earth's magnetic field disappeared or weakened, it would lead to the death of all life on the planet. Then a psychiatric hospital, then we all know how it ended.
And humanity is becoming more and more dependent on electrical energy. Mobile communications, computers, televisions, microwaves and other items of our daily life. This makes a person a cell in a huge network for the production of electromagnetic fields aimed at maintaining a "protective shield".
There are suggestions that the Egyptian pyramids, as well as structures in China, Bosnia and elsewhere, were some kind of power plants. Perhaps they fed on just the energy of the sun, the access of which to the Earth is blocked today. And they produced not electricity, but energy of a different kind?
One thing pleases, the magnetic field is decreasing, solar activity is growing, so everything goes on as usual. The shield will be broken! The sun will not leave his sons.
Thanks, good luck everyone!

In a good hour, said and heard! In a good hour! I really hope so and believe!
Good article! Good theory, I'll take it into account)
“Mind manifests itself through Light. The Mind of your Sun holds your Solar System in its energy field. The events currently taking place are related to a source outside of your Sun. Your Sun's impact is not strong enough to break through the vibrational shield around your planet right now. Therefore, other Suns come to the aid of the Sun of the Earth. Your Sun shoots out prominences like tentacles that attract cosmic rays, trapping and integrating them into the solar system. These cosmic rays are solar prominences from the Central Sun, located far in the center of the galaxy. A whole company is organized against the Sun by a certain group of beings, not interested in the spiritual development of mankind, as if the creators of your world had flaws in their developments and made a mistake by placing the Sun in the center of your Solar System. A similar idea is imposed on people by both scientists and doctors. And you people - just to prove your stupidity and how controlled you are - believe everything you read. There is nothing terrible in the fact that the ozone layer around the Earth is disappearing. … Holes in the ozone layer allow energies of different quality and light spectrum to penetrate into the Earth's atmosphere. When a new energy absorption spectrum manifests itself on a massive scale, a chemical response occurs deep within the human body. Light energy radiation changes the body at the subatomic level, contributing to your further spiritual development. In this way, humanity as a sentient species will become much stronger.” This is an excerpt from Barbara Marciniak's book Earth. Pleiadian Keys to the Living Library.
I disagree with most of the author's positions. Magnetic fields play mainly a protective role, deflecting cosmic flows of charged particles and hard radiation. If it wasn't for him, we wouldn't exist. Another thing is that we live in the Earth's magnetic field and are connected with it by our energy fields. The magnetic field affects many biological processes in nature and in living organisms.
All changes in the Earth's magnetic field are reflections of changes in the electromagnetic and material components of the new outer space, which our solar system has recently entered, as well as changes in the solar radiation spectrum. And it's not even the ozone hole. The ozone layer, in general, plays a secondary role, you can live without it. The ozone hole or depletion of ozone in the atmosphere occurs under the influence of UV radiation. Longer wavelength UV rays create ozone, while shorter wavelengths destroy ozone. The concentration of ozone depends on the balance of these radiations. But new solar radiation affects our lives. This is a large set of high-frequency linear and torsion radiation. The most amazing thing is the appearance after the six thousandth absence of intelligent torsion energies — the creators of the World. Don't confuse them with GOD. Energies carry information, plans and orders. Today they determine many changes in nature, in man and in human society. Pay attention - some people begin to see clearly, to think about the meaning of life, the structure of the Cosmos, the true history of Russia. This group of people is gradually moving away from the material side of life. They are undergoing positive changes. There is another type of people who show aggressiveness, intolerance, lies, hypocrisy, and so on. This is a negative part of society. People are being sorted. The consequences are clear. Negativity comes with religions and many social, political, scientific and economic structures. Violent confrontations and wars arise. These are the signs of the so-called end times. There will be a finish soon.
The distribution of intelligent energies goes through the system of channels of the Suns. The chain - the Central Sun of the World - the Central Sun of the Universe - the central Sun of the Galaxy - our Sun. There are no barriers to these energies, they pass through any obstacle. And everything is predetermined. The higher plane is unshakable.
Great article, lots to think about.
I am not a very scientist and not a physicist, but the question is, why don't astronauts die in a weakened magnetic field? And on the turnover they have the so-called super abilities? Why didn't the Americans die on the moon? Well, in the end, how did the poor rover fly to Mars and its electronics were not destroyed by the "HORRIBLE" and "DAMAGE" Solar radiation?
Reply to Vitaly:
Cosmonauts, firstly, fly in a weak magnetic field, secondly, the special metal lining of the ship protects the astronauts from solar radiation, and thirdly, healthy astronauts lose their health during the flight and after returning from space they need a long rehabilitation period. Their blood composition changes, adverse changes occur in the joints and bone tissues, etc. Some astronauts become disabled. They do not have any supernatural abilities in flight. There are elements of mental disorders and hallucinations.
The worst thing about astronautics is one fact. Americans have never been to the moon. Even today, such a flight with a landing on the moon is an extremely difficult task. And then this task was absolutely impossible. It was possible to land astronauts, but it was impossible to take them back. I'm afraid the same story with the rover. Already very "Martian" surface resembles the Rocky Mountains in Nevada. In addition, many vehicles launched into deep space disappeared, or went off course, or functioned in a limited way. This is the influence of solar radiation, especially during the period of solar activity.
And my addition to Irina. Her layout by Barbara Marciniak is very revealing and interesting. This woman actually receives mental information from one highly developed human consciousness from outer space in order to warn earthly humanity about the upcoming changes. She catches this information superbly. I should envy her. But her low educational level does not allow her to qualitatively analyze the information and process it into a simple verbal form. But still, her writings are very useful and informative.
I am very glad, Albert, that you spoke so well about what Marciniac is taking. The information in her books helps to change consciousness and break stereotypes so much that sometimes brains start to sparkle, burning thought patterns.
And further. It's great that you confirmed the information that there were no astronauts on the moon. If I'm not mistaken, it seems that Drunvalo Melchizedek in his book "The Ancient Secret of the Flower of Life" says that a person in a physical body cannot overcome large distances in space due to the rigid binding of our consciousness to the Earth and with the current way of perceiving time and spaces. If he decides to do this, then having flown away from the Earth at a certain distance, the person will simply go crazy.
I support the position of the author completely. There is only one conclusion - to demagnetize all these artificial magnets, to destroy their technogenicity - the fiend of hell. A simple logical analysis of the successive actions of the financial authorities. structures on Earth, gives reason to believe that they constantly maintain magnetization, and one might even say, even enhance it, thereby destroying biosystems, including humans. The sun is always depicted as the basis of the life force of the Earth and nature, and also as the heart (engine) of man. Only it can give us strength and reason. Therefore, forces alien to our Universe, having closed us from our source of strength, deprived us of will and reason, pumped the space with false information about the so-called science and art, about their science and their anti-art, harmful to earthlings. We are in this special prison, degrading every year. But in recent years, with the advent of a new era, they are very afraid of the sun breaking through this magnetic pie and bringing a photon cloud of light to earthlings, awakening all our sleeping possibilities, which will make us completely invincible, and they will evaporate from space, even their black glasses will not help them .
The Sun has a definition - it shone more, a lamp,
it is not mentioned about him - a star in the book of Genesis 1: 1-31.
If you think about it, then the regulation of the lamp is possible,
halo fields protecting the Earth and other planets from increased activity. And in general, so that and no matter how
revolved around the Sun, the geocentric worldview is the main thing, since the Earth with the Solar
system are the center of all cosmic
space. You are smart for asking such questions.
and still want to figure it out.
Earth is the only planet known to us that can be safely called inhabited. Today, this is the defining moment that distinguishes our space house from similar objects. However, interesting facts about the Earth are just beginning with him. Despite the fact that the answers to many of the secrets of the planet are literally under our feet and above our heads, scientists still cannot explain a lot. On the other hand, among the accumulated information there are sometimes more surprising facts than other events in deep space.
Things of bygone days
For the distant ancestors of any nation, everything on Earth was evidence of the presence of supernatural forces: gods, spirits, fairies and sorceresses. However, even in the epoch most remote from us in time, inquisitive minds were discovered who sought to explain what was happening differently. They found patterns, learned to predict certain phenomena, created theories about the structure of the world. The myth of the Earth resting on the backs of huge animals, which arose in the course of such attempts to understand the surrounding nature, is unusually tenacious. It is still found, for example, among the Indians. According to their model of the universe, the Earth rests on the back of a turtle and shudders every time it takes a step.
Trembling of the earth
Of course, such an explanation of earthquakes does not satisfy scientists. Today, almost everyone knows that the cause of this phenomenon is the movement and collision of tectonic plates. However, there are many facts associated with earthquakes that are not known to the majority, and some of them still remain inexplicable.
Interesting facts about the Earth include, for example, the following statistics:
- annually around the world there are about 500 thousand earthquakes, and every day their number reaches 8 thousand, but most of them are imperceptible;
- noticeable to humans occur about 55 thousand times a year;
- earthquakes that bring destruction and have a magnitude of 5 to 8.9 points occur no more than 1000 times a year;
- the most catastrophic in their consequences, fortunately, are very rare - about once every 20 years.
Interestingly, the complete disappearance of earthquakes, as well as volcanic activity, will mean the cessation of tectonic activity. This is possible after the completion of all processes that take place in the bowels. Strange as it may seem, this is very undesirable for a person, since it is a sign of the end of the differentiation of the interior, and hence the loss of the Earth's main source of energy that "warms up" it. We can say that earthquakes are a sign of the life of the planet.
Strange outbreaks
There are also quite unusual facts about the Earth associated with the shaking of the firmament. According to many eyewitnesses, such phenomena are accompanied not only by destruction and shocks, but also by bright flashes. Italian physicist Christiano Feruga collected a large number of references to such phenomena, covering many sources up to 2000. However, scientists paid attention to this evidence only after the publication of photographs taken during the earthquake in 1966 in Japan.
Today, there are already many such images. Sometimes it is quite difficult to understand whether it is a fake or not. However, no explanation for the phenomenon has yet been found.
supercontinent
The cause of volcanic eruptions, earthquakes, and mountain building lies in the movements of tectonic plates. It also leads to what scientists call continental drift. Thanks to this process, interesting facts about the Earth are supplemented by information about the existence of several supercontinents in the distant past, which broke up and “gathered” again after a while, but in a slightly different configuration. The last of them is called Pangea. However, the most interesting thing about the Earth in this perspective is that the process continues at the present time. every year they overcome a distance of several centimeters, that is, in the future, after about 250 million years, a new single continent will form.
moving stones
What the movement of tectonic plates does not explain is the changing position of strange rocks in California's famous Death Valley. They are on the surface of a dried-up lake and leave clear traces, slowly moving along it. Numerous studies and observations have given small results - scientists are still unable to explain. It is only known that in 7 years they overcome about 200 m, but no one has ever seen how they move. The greatest "activity" of stones falls on the winter period.
Miracles are near
Unusual stones are also found in Kolpnyansky. They periodically begin to grow, like seedlings. Some locals treat the boulders as sacred. It is believed that touching them bestows strength and health.
Earth's magnetic field: interesting facts
If you look at the photo of the stones from the Death Valley, it may seem that something is attracting them. Involuntarily, it is remembered that our planet is a kind of huge magnet. Interestingly, the occurrence of the Earth's magnetic field also belongs to the category of facts without an unambiguous scientific explanation. The main hypothesis says that it is generated by the liquid part of the core, which consists of alloys of iron and nickel. However, such a hypothesis cannot explain all the facts.
The researchers found that cooling lava can tell about the direction and strength of the magnetic field. Its samples of different times were studied. It turned out that the strength of the field in some periods of the planet's history significantly decreased. This fact, as well as the dependence of the field on is explained by another hypothesis of the origin of the planet's magnetism. According to her, the water-air ocean plays the main role in the process. Water, evaporating, becomes electrified and receives a positive charge. At the same time, negative ions accumulate in the earth. Due to the rotation of the planet, a stream of charged particles is formed, that is, in fact, a current. And, as is known from the school physics course, where there is an electric current, there is a magnetic field.
The work of human hands
Many incredible facts about the Earth owe their appearance to people. Unfortunately, quite often they have a negative connotation. There are also cases in history when the decision of a small group of people led to rather strong changes in the landscape. An impressive example of this is the Gates of Hell in Turkmenistan. It is a deep chasm in which the flames rage. Approximately 35 years ago, gas was developed here. In the process of mining, the site on which the camp of geologists was located collapsed into a deep cave. There were no people who wanted to go down for things, since the entire hole that had formed was filled with natural gas. They set him on fire. It is still burning, and it is not known when this man-made miracle will cease to please and frighten the locals.
Interesting facts about the Earth can be listed endlessly. With the development of science, an explanation of an increasing number of mystical phenomena and simply strange natural processes appears. At the same time, research contributes to a treasury of curious information: every year, scientists discover something new, the existence of which they had no idea.
Humanity has achieved a lot. Because of the favorable environment, people can reproduce and exist. But all the same, the planet inhabited by people and all living things retains secrets and mysteries, emphasizing that not everything is still in the power of the most intelligent being. Perhaps new discoveries will help to better understand the strife taking place on Earth and restore the necessary harmony.
10 The only place to live
To date, Earth is the only planet where life exists. Scientists sometimes present evidence of the presence of certain sources on Mars and Titan, talking about amino acids in space, the discovery of water, and organic molecules. However, intelligent beings similar to earthlings have not been found in the universe. It is certainly pleasant and at the same time responsible. Although many in relation to the planet behave obscenely and litter it in every possible way. The planet must be protected by participating in small subbotniks and actions to protect the environment.
9 The only satellite
The only satellite of the Earth is the Moon. A man has visited this astronomical object, so a lot is connected with it. They try to describe and calculate the movement. It is known that the moon does not glow. It only reflects the light of the sun. It turns out that earthlings can see the lunar surface, which is illuminated by the sun. Appeal to the Earth - only one side. This is due to synchronization: simultaneous movement around the axis and the Earth.
8 wrong shape
The earth does not have an even round shape. When the Earth rotates, gravity is shifted to the center, and centrifugal forces are directed to the side. Due to rotation, a bulge is created at the planet's equator. The result is a difference in diameters and the equatorial one exceeds the diameter between the poles by 43 km. The consequences of imperfection affect the distribution of mass. Fluctuations in mass contribute to fluctuations in gravity. The result of all this is catastrophic: melted glaciers, climate change and other consequences. Changes for the planet are a kind of stress.
7 Magnetic field
Hot and liquid metal is concentrated around the iron core of the planet Earth. The presence of a magnetic field is just obtained due to the flow of liquid metal, which created an electric current. If there were no magnetic field, particles of the sun would constantly shower the planet. Earthlings suffering from excessive radiation would simply all die. The researchers found that the north magnetic pole has moved from its place, and the speed of this movement has increased significantly (almost four times at this time).
6 Length of the year
Many people remember from the school curriculum that the year is 365 days. However, this is not an exact figure. A four-digit balance in the sum for 4 years adds one more day - February 29th. Years that are divisible by 100 and at the same time are not a multiple of 400 (1900, 2100, etc.) do not fit these calculations. The year is called a leap year and carries magical predictions of failure or big changes. Translated from Latin, a leap year is called "Two Sixes". Hence, apparently, a fearful attitude towards him, which provides the inhabitants of the planet Earth with an extra day.
5 Rest at the same time as movement
If a person is at rest, he still moves thanks to the Earth, which rotates around itself and the Sun at the same time. Why do people not feel the movement of the planet? Simply because the Earth is very large, and it is impossible to measure its quiet sliding. However, the change of day and night, the gradual transition from one season to the next - this is the movement of the Earth.
4 Stones can walk
There is a place on planet Earth where huge boulders are constantly moving. In Death Valley, on the surface of a dry lake, the wind shakes rocks when the clay surface becomes wet. During the melting of snow, large stones seem to be walking. The stones leave a kind of road and its trajectory is impossible to predict. The Valley of Death got its name because of the hot climate. During the gold rush, gold miners suffered from high temperatures in the air. The desert was strewn with dead bodies. Who was stronger, were able to endure the heat and get rich. Now the “Valley of Death” is a subject of controversy for tourists.
3 Water predominance
Most of the planet's surface is filled with water. When a man was able to visit space, the first glance was directed to the place from which he flew. The earth was reflected in blue and its second name is “Blue Planet”. Only 30% is solid bark, on which people, animals and flora are located. But apparently this territory is quite enough for the spread of all living things.
2 natural electricity
The most terrible phenomenon of nature is thunder and lightning. A person still experiences inconvenience during a thunderstorm today. A powerful electrical discharge contains voltages up to a billion volts. Lightning is subject to trees, people, animals and objects. In open spaces, one blow can warm the air up to 30,000 ° C and cause the death of a living being. Linear lightning does not penetrate indoors. Ball lightning has not yet been studied by scientists. Its rare appearance by eyewitnesses does not give a full assessment, therefore it is impossible to accurately describe the strength of the defeat.
1 flooded gold
In large seas there is a large amount of gold. If it were possible to get it and distribute it among the entire population, each inhabitant would receive 4.5 kg of the precious metal. Wealth is dissolved in sea water. One liter contains only 13 billionth part. Gold in undissolved form is located very deep, and all attempts to extract it to the surface of the earth ended in failure. It turns out that we are rich and poor at the same time.
How long the planet Earth will exist, so many people will be able to learn new stories about the place where they live. Unexplored secrets thanks to scientists are gradually becoming discoveries. At first, the emergence of man was a novelty, now it is the conquest of peaks and natural phenomena. The main thing is not to forget that your planet must be protected for posterity, so that there is someone to remember us.
Magnet and magnetism never cease to amaze humanity. We have compiled some interesting facts about permanent magnets that you may not know yet.
1. Why was the magnet called a magnet?
There are two versions of the origin of this name: poetic and not very. The first is the poetic legend of a shepherd named Magnus (or Magnes). The famous historian Pliny described that once this shepherd wandered with his sheep to a new place, stood on an unusual black stone and suddenly found that he could not tear his staff and his nailed shoes from it.
It is more likely that everything was more prosaic: once in the Greek region of Magnesia, deposits of a stone capable of attracting iron were discovered. They called it that - “stone from Magnesia” or, more simply, a magnet. However, there is also a bit of poetry here, because the region got its name from the Magnet tribe living in it, and they named themselves that way in honor of the mythical hero, the son of Zeus.
2. Meet the "Loving Stone"
It was this romantic name that the inventive Chinese gave the magnet. Representatives of one of the oldest cultures poetically described it as follows. Tsy-shi (in Russian “loving stone” or “stone of motherly love”), they said, attracts iron, just like a warm mother attracts children. This force actually extends to other metals, but less intensely.
Interestingly, the French also called the magnet the word "loving" - for both meanings, the same word aimant is used.
3. How did the magnetic board
In 2008, three American students demonstrated their knowledge, but they did not have enough space on the board to show all the necessary information, they decided to additionally use large format sheets, but the difficulty was that the paper had to be held in their hands. And then they came up with a brilliant idea to make part of the board with a magnetic surface. So there was a new technology for coating the surface for drawing with markers that are easily erased with a dry sponge. Such markers are called dry erase.
4. Who invented the first magnetic compass?
Back in the third century BC, a Chinese author described a compass in the form of a magnet spoon, but a device with a floating arrow appeared only in the 11th century. Much later, in 1300, John Gira was the first in Europe to create a compass for travelers (the magnet was brought in just 40 years before by the traveler Marco Polo), which greatly simplified the life of sailors. And the Italian Flavio Joya improved the design.
5. A little about the magnetic storm
There are days when the compass needle spins erratically instead of pointing north. Sometimes this goes on for hours, and sometimes for days. Most of all, the compass is used by sailors - they were the first to note this phenomenon, christening it a magnetic storm.
This happens due to solar flares, when more charged particles from the Sun enter the magnetic field of our planet. It is indignant, and geomagnetic storms begin, affecting both the human body and the operation of technology.
6. How to see the magnetic field?
It is quite possible to see the magnetic field, and this is taught in school physics lessons, offering the following sequence of actions:
- the magnet is covered with a glass plate;
- a sheet of paper is placed on top of the plate;
- the paper is sprinkled with an even layer of iron filings;
- the filings are magnetized, and when they are shaken, they are momentarily separated from the plate, and easily turn, forming - complex curved lines diverging from the poles.
The resulting picture looks like this: the closer to the pole, the thicker and clearer the lines of sawdust, and the farther they go, the more rarefied and lose their distinctness. This is a clear example of how magnetic forces are weakened by distance.
7. Why is the coffin of the Prophet Muhammad hanging in the air?
For more than one century, inquisitive minds were excited by the story of the levitating coffin of the prophet Mohammed. In 1600, a book about magnets was published, where the author William Gilbert conveyed the story he had heard about the Mahomet chapel. Its vault contains magnetic stones of great strength, which allow the iron chest with the ashes of the prophet to hang in the air.
The Muslims themselves considered this a miracle, and said that the reason was that the earth could not bear the corpse of such a person. In fact, some magicians have done such tricks before. But it must be said that it is impossible to maintain balance in this case. The magnet in this case is strong enough to lift the object, but it will not work to keep it at a stable distance without an additional thread.
8. Magnet and heating
Magnets have special characteristics. These include the operating temperature with maximum performance and the Curie point, at which ferromagnets lose their properties. For each alloy, these parameters are individual. For example, for magnetoplasts based on NdFeB filler, the maximum operating temperature can be up to 120 or even 220°C, while ferrites can withstand operation at temperatures up to 250-300°C, and their Curie point is 450°C.
9. Why does a magnetic tomograph see a person from the inside?
Our body consists of 60-80% H2O, and hydrogen atoms in the formula of water, under the action of a powerful magnet, begin to radiate waves. They are different because they depend on the tissues where the atoms are located, and reflect any change in our body. A person placed in a magnetic field radiates these waves, and the recorded indicators are transformed into a three-color image.
10. How does the magnetic pad work?
High-speed movement of trains of the "Maglev" type is achieved thanks to the following technology. The cars are attached to the guide, which covers the rail, or vice versa. In both versions, the cars are kept above the rail due to the vertical magnetic field, while the horizontal one maintains alignment. Electromagnets are also placed on the rail, with which the operation of the engines is ensured - this is how acceleration and braking occur.
11. Peter Peregrine and the Magnet Message
In the second half of the 13th century, a certain Pierre Peregrin de Marricourt wrote a treatise letter to a friend, in which he spoke in detail about the properties of a magnet and even suggested using it as a perpetual motion machine (then this idea was popular in France, in the scientist’s homeland). Almost nothing is known about the author, but his contribution for the first systematic study in Europe is highly valued even today.
The treatise talks about the presence of poles in the spherical samples that were used, the magnetization procedure, the interaction of magnets and many other points related to the properties of magnets. Marricourt was sure that the stone he was examining concealed a semblance of a celestial sphere with its poles.
