Van Allen belts
Magnetic domains.
Placing the material in a strong magnetic field will align its' domains. You can swipe a metal tool on a magnet and make it a magnet.
Magnetic domains have the tendency to align with magnetic fields. The Earth's magnetic field is relatively weak, but I would expect SOME alignment.
Yes. When a material is magnetized the magnetic domains are aligned.

Domains inside the magnetic
Domain theory suggests that small pockets of atoms (domains) in the nail are initially randomly and chaotically aligned (making it non-magnetic). But in a strong magnetic field the domains are forced to align, if the field is strong enough they will stay like that for some time. There are differing theories about why the domains make it magnetic I think the accepted one is that the electrons in each atom of iron in a domain are spinning the same way, and when all the electrons in the nail are spinning the same way it makes the whole thing magnetic.

In non magnetized material the domains are not ordered -they do not align with one another.
The domains in a magnetic material is aligned unlike the non-magnetic material which is scattered
Without magnetic domains a magnet wouldn't have its magnetism. Magnetic domains are clusters of iron atoms that line up in the smae direction when magnetised. When unmagnitized the iron atoms scatter.
Magnetic field
"magnetic"
Iron has magnetic domains, that tend to align when the iron is in a magnetic field. Many other materials don't have such magnetic domains.
