I have some information on reversals:

Reversals may take a few thousand years to occur. The cause of reversals relies on the theory of relativity. Electrons on the surface of the earth have no relative velocity to us on the earth surface as it rotates. The normal field is due to electrons, and as they move outward, the normal field will decrease; and if they move inward, then the normal field will increase because of relativity. Thus, the reversal of Earth’s magnetic field is controlled by the inward or outward motion of the spherical shell of electrons.

But I don't know what these electrons are? Are they the electrons on the surface of the earth? Would anyone be able to help me? Thanxxx!

There are no electrons involved here, for magnetism has its own units called magnetic lines of force or magnetic field. Also, magnetic reversals have nothing to do with the Theory of Relativity. Finally, ignore anything that Lion_of_Judah said, he speaks through the Bible, which is not a book on science.
Since the Earth's magnetic field is due to the nickel-iron core of the Earth, it cannot be studied directly. Magnetic field lines of force are called Flux and the strength of the magnetic field is called Flux Density. One line of force is called a Maxwell and one million lines of force is called a Weber. These units are named for pioneers in that branch of Physics dealing with the Electro-magnetic (EM) Spectrum. It was Maxwell who brought all the research together and came up with a theory that unified electricity and magnetism. There are parallels within electricity and magnetism, but they are two different parts of the EM Spectrum. As the sun radiates EM waves, the electro part is 90 degrees to the right of the magneto part when the wave approaches the Earth.

4 good motives to no longer subject. a million/ it incredibly is basically an hypothesis subsequently low possibility at modern-day 2/ If this happens, it is going to teach some first sign that have been nicely pointed out the two in previous reversal and in fashions. i.e. there'll be type of mini-pole on countless place of the earth, it incredibly is not a ten-20 years job yet one thousand-2000 years if not extra. while geologists says it incredibly is instant, it ability that. 3/ If it became into instant, there'll be very few motives to stress, it's going to be in ordinary terms a metamorphosis of polarity, like placed a minus rather of plus. 4/ there is no longer something to do to alter it in spite of if all of us comprehend it, with the present technologies. we can not ward off it, basically mitigate it.
