Does Earth have a magnetic core?

Question

Is the magnetic field of Earth produced by its central magnetic core?

Does the field exert a magnetic force on all electrons on Earth?

I could use a webpage on the subject.

Answer 1

Yessss... it is called the magnetic field. And try googling it.

Answer 2

why don't you try wiki.

And yes, the B-field would impact all electrons.  If they are moving, there is a regular old qv x B force.  And even if they aren't moving, the electron has an intrinsic magnetic moment, so the earth's B-field can cause the spin to precess.  But the magnetic field of the earth is teeny tiny compared to the fields the electron feels in an atom or a solid, so most electrons aren't going to notice too much.

Answer 3

i think it's not central

its polar magnetic poles

the only reason compasses work is because the magnetic pole pulls it north therefore you get the direction, but soon he compasses will point south since the magnetic pull changes every some decades or centries

Answer 4

Earth is basically a big iron ball, and it has a magnetic core as a result. Technically, its magnetic field slightly affects every electron everywhere, but can't overcome binding forces. Thus, nothing flies apart.

Answer 5

Yes, it does, and yes, it does.
