What Are the Basics of Magnetism and Its Mysteries?

[Questioner...]

Hello,
I've come to terms that I am fascinated with magnets and how they work. I thought I would come here to ask some questions before I go out start a search on my own.

What I know:
A magnet is a medal:), It does not attract objects that are not medal. The Earth's core is basically a giant magnet.
-I know it's a lot of information to cope with.

Questions-
How does a basic atom of a magnet look like? Could we increase the number of electrons to increase the power of the magnetic field? Could Earth's iron core be the possible source of gravity being a giant magnet- seeing that we ourselves and nearly every object held to the Earth consists of small amount of iron? Could a Huge source of magnetic power attract such small amount of iron and such?

How about reading wikipedia at http://en.wikipedia.org/wiki/Magnetism

Magnetism is a vast subject with many interesting and strange alleys for investigation... including electron spins...and electricity...

Why are some materials magnetic and others not magnetic? You can deduce that from the wikipedia article and it may be described there as well...
