There is a magnetic field on both levels of the earth, how does that exist?

1. Is there really a magnetic field bump at the poles?

Yes, it really exists. In 1845, the German mathematician Carl Gauss began to record data on the Earth's magnetic field, which is nearly 10% weaker today than then. And that momentum is set to continue.

The Earth's magnetic field has flipped several times over the past billions of years, and this can be found in a wealth of evidence in Earth's rocks.

And the computer simulation system they have developed in recent decades can be a good demonstration of this flipping process. Gary Grazmeier, an expert in earth sciences and magnetic fields at the University of California, said: "We can see the flip on the rock, but the rock won't tell us why."

A computer simulation system can explain it all. The system was developed by Grazmeyer and his colleague Paul Roberts.

According to the geological record, the Earth's magnetic field flips on average about once every 200,000 years, although the time can vary greatly and is not fixed, and the last time the magnetic field flipped was 780,000 years ago.

2. What problems will arise when the poles are inverted?

Many of the animals that migrate by identifying the Earth's north and south poles will be "out of order".

For tens of thousands of years, bees, pigeons, whales, salmon, red turtles, Zimbabwean moles and other animals have relied on their innate instincts to move back under the guidance of the magnetic field, and once the magnetic field is gone, their fate is difficult.

Many creatures that rely on the Earth's magnetic field to navigate, such as swallows, antelopes, whales, pigeons, and magnetotactic bacteria, can be disoriented.

3. What happens when the poles are inverted?

The liquid material around the Earth's core is always in a state of instability, rotating at a very slow rate, usually about once a year. However, when subjected to some kind of interference, this speed will become faster and faster, causing the original magnetic field to deviate farther and farther away from the poles, and finally the phenomenon of the North and South poles being swapped.

There are magnetic fields at both ends of the earth, and you can compare the earth to a magnet, and you can understand it.

The Earth can be seen as a very large magnet, so its poles will have magnetic fields.

Some scientists have shown that the Earth's poles have a magnetic field, and it also flips.

Because the earth is like a magnet, there will be magnetic fields at both poles.

The magnetic field at the Earth's poles is generated by the Earth during its natural development.

There is a liquid substance around the center of the earth that is in an unstable state. When he is disturbed, the speed will get faster and faster. A magnetic phenomenon caused by the original magnetic field drifting farther and farther away from the poles.

The magnetic fields at the poles of the earth are naturally occurring in response to change.

There is a liquid substance around the center of the earth that is in an unstable state.

It is a magnet produced by the continuous evolution of the earth over hundreds of millions of years.

The earth is equivalent to a large magnet, and the magnetic field that exists around it is called the geomagnetic field; The geomagnetic field consists of two parts: the basic magnetic field and the variable magnetic field. The basic magnetic field is the main part of the geomagnetic field, which originates from the interior of the solid earth, is relatively stable, and belongs to the part of the static magnetic field. The variable magnetic field includes various short-term changes in the geomagnetic field, which mainly originate from the outside of the solid earth and is relatively weak.

Geomagnetic field refers to the natural magnetic phenomenon that exists in the interior of the earth. The Earth can be thought of as a magnetic dipole with one pole near the geographic north pole and the other near the geographic south pole. The imaginary straight line (magnetic axis) through these two poles is tilted approximately to the Earth's axis of rotation.

The Earth's magnetic field extends tens of thousands of kilometers into space, forming the Earth's magnetosphere. The Earth's magnetosphere acts as a barrier to the Earth from charged particles carried by the solar wind. The Earth's magnetosphere is squeezed by the force of charged particles in the daytime region (sunward side) and extends outward in the Earth's nocturnal region (backsolar side).

The magnetic field is a special substance that cannot be seen or touched, the magnetic field is not composed of atoms or molecules, but the magnetic field exists objectively. The magnetic field has the radiative properties of wave particles. There is a magnetic field around the magnet, and the interaction between the magnets is mediated by the magnetic field, so the two magnets can act without contact.

An electric current, a moving charge, a magnet, or a special form of matter that exists in the space around the changing electric field. Since the magnetism of a magnet is the same as the current, the current is the movement of an electric charge, so in a nutshell, the magnetic field is generated by the change of the moving charge or electric field.

The direction of the geomagnetic field is from the north pole of the earth to the south pole of the earth.

The earth itself is a huge magnet, and the magnetic field around the earth is called the geomagnetic field; The magnetic north pole is near the geographic south pole; The geomagnetic south pole is near the geographic North Pole, but it does not coincide.

The earth itself is a huge magnet, and the magnetic field around the earth is called the geomagnetic field, the geomagnetic north pole is near the geographical south pole, and the geomagnetic south pole is near the geographic north pole, so the direction of the geomagnetic field is from the geomagnetic north pole to the geomagnetic south pole.

The origin of the Earth's magnetic field

The hypotheses about the origin of the geomagnetic field can be divided into two categories: the first type of hypothesis is based on existing physical theories; The second type of hypothesis takes a unique approach, arguing that for a cosmic object such as the earth, there are special laws that are different from the existing known theories.

The first type of hypotheses include the rotational charge hypothesis, the geomagnetic field hypothesis with the earth's core as a precondition, the drift current hypothesis, the thermal effect hypothesis, and the Hall effect hypothesis.

1) There is the rotational charge hypothesis that there is an equal amount of opposite-sex charge on the earth, one distributed in the interior of the earth and the other distributed on the surface of the earth, and the charge rotates with the earth, thus creating a magnetic field.

2) The geomagnetic field hypothesis, which presupposes the earth's core, holds that the formation of electric current in the earth's core should occur by induction when the metal material in the earth's core moves vortex in the magnetic field. At the same time, the field in the form of the electric current itself is a continuous regenerative magnetic field, as in the case of a generator.

Because of the fear that changes in the earth's magnetic field will cause deserts to become oases, and oases to deserts, and there may be some places that may be flooded overnight or in a day. The closer you get to the critical point, the faster the change, and it is important to detect it early and move it out as soon as possible. So I've been observing and studying the Earth's magnetic field all this time.

After observing it for a while, I suspect that the direction of the sun is now a little off, and the direction of the deviation is northwest. Because I don't have advanced instruments to make observations, and I won't use advanced instruments to make observations. It's just looking with my eyes, so I'm not sure.

I only write it out for reference, and I hope that experts and scientists in this field can observe it and make accurate data.

Then after this period of observation, I found that the water level is in the northeast direction**, and the water level in the southwest and northwest directions seems to be slowly declining, and it may not be the critical line now, so the direction of ** and the direction of decline are relatively slow, and it will get faster and faster when it is close to the critical line, right? It could also be that I wasn't seeing accurately enough with my eyes. It is hoped that experts and scientists in this field will observe accurate data with advanced instruments.

Identify areas that would be flooded overnight or a day, and move people out early.
