Yes, in fact, the question of the origin of the earth's magnetic poles, so far it is all speculation, no one has very sufficient physical evidence to explain how the earth's magnetic poles came about, why do I want to say the origin of the earth's magnetic poles, because there is a theory that the earth's magnetic poles are due to the rotation angle velocity of the earth's core and the rotation speed of the earth's crust, we know, the earth's core is a solid state, and the outer core is a liquid state, that is, we know the magma, so if once the rotation angle is not the same, An electromagnetic field is formed. That is, our North and South Poles, but if this statement is true, you can imagine that the rotation speed of the Earth's core is greater than the rotation speed of the Earth's crust, which will produce friction, and the Earth's core will inevitably transmit angular momentum to the Earth's crust through the mantle asthenosphere material, and the result is that the rotation angular velocity of the Earth's core gradually decreases, and the rotation angular velocity of the Earth's crust gradually increases. After all, there will be a moment when their number of degrees will continue, and then the earth's poles disappear, but due to the law of inertia, the angular velocity of rotation of the earth's crust continues to increase, and the angular velocity of rotation of the earth's core continues to decrease, so that the angular velocity of rotation of the earth's core will be less than the angular velocity of rotation of the earth's crust, and the two levels are just the opposite.
Going back to your question, the reversal of the magnetic pole affects the compass, which you said very correctly, but the physical South Pole and North Pole are named by us humans for the earth, and the compass compass still refers to the north, and this north and south are also named by human beings. In fact, we can call it whatever we want, but the geographical North and South Poles will not change. The only thing that can be changed is the magnetic poles.
In the end, I want to say that the possibility of this reversal must be based on the premise of the formation of the earth's magnetic poles, and what you have written above is human speculation, in fact, I personally think that there are many loopholes in this statement, such as the north and south poles of the earth in summer, winter and switch strength, if the earth's magnetic field is really caused by the difference in angular velocity between the earth's core and the earth's crust, then the magnetic field strength should be a fixed value. There will be no switching between strength and weakness. So now human beings are more and more inclined to the formation of the earth's magnetic field is caused by the outside world, such as the solar wind with electrons.
So I can explain why I switch between strength and weakness in summer and winter, because perihelion and aphelion. These are also my own ideas, I will not impose them on you, you can consider them when you have time, after all, mankind has not yet proved the cause of the formation of the earth's magnetic field, maybe you are the next physicist to solve this puzzle. Hehe.

The magnetic pole has nothing to do with the geographical position, if it is really reversed, the North Pole is still the North Pole, and the magnetic North Pole appears near the geographical South Pole, but if the magnetic pole is suddenly reversed, it is estimated that we will choke enough, and human beings may perish, and the consequences are terrible.
-
There are three types of geographical north and south poles: map north and south poles, true north and south poles, and magnetic north and south poles. You've confused the relationship between the three!
Don't be stubborn about your explanation, you should first check the meaning and relationship between the three!
-
The geography of the North and South Poles will not change the narrative because of this! Just rename the compass, the compass! Everything else works fine! Because things on the surface of the earth haven't changed! So the geographical name doesn't have to change!
-
The geography of the North and South Poles will not change.

Don't think too much, 2012 won't be the end.

No, it won't. Not explaining is too simple.

The Earth's north and south magnetic poles are not fixed, and it takes 7,000 years for the magnetic poles to reverse.
1.Earth's magnetic field.
The North and South Poles of the Earth were created, but it was not fixed. In fact, the magnetic field is very active; It sometimes weakens, or even reverses, causing the Earth's poles to reverse. However, this reversal does not occur very often, about once every 100,000 to 1 million years.
That's why this phenomenon remains largely a part of the mystery for scientists. However, there is a study that may help researchers better understand how long the Earth's magnetic field reversal lasts and how complex it is.
2.In the process of flipping the poles, many aspects of life on Earth are upside down and chaotic. At that time, the Earth's magnetic field was completely gone, and the Earth was exposed to all sorts of deadly cosmic rays.
Rely on protecting humans from the intense radiation of solar high-energy particles; It will heat the upper layers of the atmosphere.
contribute to global climate change; sabotage of all navigation and communication satellites in the Earth's near-earth orbit; In addition, it will lose the orientation ability of all migratory animals on the planet.
3.The Earth's magnetic field is weakening, and many scientists are analyzing the laws of ancient geomagnetic changes through the study of ferromagnetic minerals. Taiwan University, China.
Shen Chuanzhou, a professor at the Department of Address Science, believes that karst terrain.
The stalagmites in may record the geomagnetic direction during the long growth process because they are the groundwater dripping from the top of the cave. Some scientists even believe that the Earth's magnetic field, the Earth's main protective shield, could be weakened to 5% or less.
4.Due to the geomagnetic field.
The presence of a large number of high-energy rays from the Sun to the Earth (solar wind.
Distortion in the vicinity of the Earth, on the one hand, prevents the solar wind from directly touching the ionosphere, so that the ionosphere does not escape. On the other hand, at the top of the atmosphere, ionization escapes occur from some gas molecules, such as oxygen ions and hydrogen ions. The ground-based magnetic field can send ions that are about to escape back into the ionosphere to maintain the stability of the air.
That's the answer to that question.
-
It will take at least 250,000 years. It's a very long process, and the angle of the offset is very small each time.
-
It is said that Clement discovered through his research that it takes about 7,000 years for the magnetic poles of the earth's magnetic field to reverse.
-
The magnetic field is very active, according to scientists' research, the earth has not changed its magnetic poles for 700,000 years, but in the past 4,000 years, the magnetic field is weakening sharply, and the strength has lost half.
-
On the outside of the Earth, magnetic inductance lines come out of the geomagnetic north pole and enter the earth at the geomagnetic south pole. Therefore, as depicted in the diagram, the earth is round, and the magnetic inductance lines must be drawn elliptically, and the radius of curvature of the two is different.
The two men are located in the northern hemisphere, about Beijing, with the top of their heads, the north on the left, and the south on the right.

The structure of the earth is complex, and the polarity of its internal magnetic field is constantly changing, but, generally speaking, the location of the geomagnetic south pole near the north pole of the earth is due to the strong reversal of the earth's internal magnetic field, that is, the earth's internal magnetic field changes from the original north pole polarity to the south pole polarity. This anti-** was born at a certain time in the history of the earth, which may have been 2 million years ago or 100,000 years ago, and it is not completely certain. The Earth's magnetic poles have been reversed many times, each time at a different and uncertain time.
-
Because the north and south poles of the compass have been replaced, the compass becomes the north arrow, and in this case, the magnetic poles are reversed.
-
It is a physical phenomenon that is uncertain in what exactly it will happen, and it can change in an instant, and at the same time it can cause a violent disaster.
-
Exactly under what circumstances will cause a reversal is uncertain, some people think it's a split second thing, others think it's a slow process.
-
The north and south poles are determined by the Earth's axis, artificially named, and do not change, but the magnetic poles do change due to the Earth's internal causes (the Earth's magnetic poles have changed several times in history).
-
The geographical north and south poles are not reversed, but the geomagnetic north and south poles change periodically.
-
The north and south poles will not be reversed, you are talking about the magnetic field being reversed, and it is possible for the earth's magnetic field to happen
-
The earth is divided into north and south poles, and its rotation is centered on the earth's axis that runs through the north and south poles. If we reversed the north and south poles of the earth, what would happen to the earth?
-
The reversal definitely has an impact on Earth, but it hasn't been recorded yet, so it's all speculation. However, guessing and guessing, it is still necessary to guess reasonably and reliably, and I hope that readers and friends will keep their eyes open, judge carefully, and don't seem to be accurate and open-mouthed. The reason for the reversal of the Earth's magnetic poles is the Earth's interior.
In the previous question, I pointed out that the magnetism of the Earth does not come from the iron core, but from the orderly movement of the microscopic matter inside the Earth.
<> that is, the reversal of the Earth's magnetic poles is caused by the quantitative to qualitative change of the microscopic material in the Earth's interior. According to the fact that the Earth is a celestial body of heavy elemental matter, it is indicated that the Earth belongs to the aging of celestial bodies. It also shows that the changes in the microscopic matter in the Earth's interior are decay and degradation.
Although the reversal of the Earth's magnetic poles will not have a direct impact on the Earth's surface, due to the large reduction of microscopic matter in the Earth's interior, it will lead to the arrival of disasters such as ultraviolet rays that have not yet been mastered by the magnetic protection of the Earth's outer space.
Therefore, the reversal of the Earth's magnetic poles is not a good thing, but the aging of the Earth and the reversal of the Earth's magnetic poles are irreversible, so it is not sensational, but should be the focus of scientific research. When the earth rotates, the polarity of iron is adjusted to the same direction as the earth's axis, and it is swayed by the earth's motion, and always maintains a certain angle with the earth's axis. The magnetic poles change as the position of the earth's axis moves.
The melting of glaciers at the poles causes the position of the Earth's center of mass to shift, which in turn causes the position of the Earth's axis to shift, resulting in a change in the direction of the magnetic poles. Not all iron polarity changes at the same time. Some iron has a slow change in polarity.
As a result, some of the polarity of iron is confused or lost during the transfer, resulting in a weakening of the strength of the Earth's magnetic field. The magnetic pole transfer is not a north-south reversal, but a deflection that occurs with the shift of the Earth's axis.
To put it simply, you know what a magnet is, then the inside of the earth is equivalent to a rectangular magnet, he has the south pole and the north pole, also called the geomagnetic south pole and the geomagnetic north pole, we usually say the south pole and the north pole refer to the geographical south pole and the north pole, the geomagnetic south pole is against the geographic north pole, the geographic south pole is against the geomagnetic north pole, if the geomagnetic conversion, it becomes the geomagnetic south pole against the geographic south pole, the geomagnetic north pole is against the geographic north pole, there are many phenomena on the earth caused by the magnetic field generated by this magnet, like tides, **, tsunamis, or it could have been influenced by him. >>>More
