Why certain things are easier to magnetize than others?

[Biologik]

Here is what I understood from an email I got.

Rubber is hard to magnetize because the electrons in its' ''inner shell'' are tightly bound to the atom, making it hard for them to ''go free'' and align with other electrons to conduct electricity and become magnetized?


Please be detailed.

But not to detailed.

Uhm yes and no, keeping in mass is already "full" of electricity, but not potential difference you must remember that electrons are moving through materials- infact the more heat the more they (free electrons) are moving around and producing magnetic fields. As explained in a recent article on physorg the electrons in magnets have similar spin as they move through it. In copper they have very varied spins so they cancel each other out. Perhaps the reason water is diamagnetic is free electrons on one side of atom work like a gear- a reaction occurs on the other side of the molecule but it is in reverse- and that perpetuates until it has traveled through the diamagnetic material, but who knows I am just theorizing off recent info on physorg =)
