What does the Earth's magnetic field do?
2006-09-02 04:59:46 · update #1
It causes a force to exist between the north and south poles of the magnet generating the field.
Aside from that, magnetic fields don't do much of anything unless they're in motion.

Our magnetic field saves our life. without the magnetic field there would be no Van Allan belt and we would all die from radiation.
Some think that the magnetic field comes from the molten core WRONG . U take a way to measure magnetic fields and start to heat the magnet and u would loose almost all the magnetic field.

as u are at level 2 i assume that u are in touch with spintronics. As we know that the earths magnetic field is caused by the spin of the plasma inside the earth. This spin of plasma may effect the spin of other planets or other bodies.Plasma is The 4th state of matter. so the spin causes the magnetic field of earth to influence the domains in a magnet .Since Fe3+ ions union is seen as predominantly plasma it exhibits the highest ferro magnetic properties so what ever properties of the spinning electron .every thing applies to earth....
