Interesting Magnet Fact:
Ferromagnetism: When a ferromagnetic material is placed near a
magnet, it will be attracted toward the region of greater magnetic field.
This is what we are most familiar with when our magnet picks up a bunch of
paperclips. Iron, cobalt, nickel, gadolinium, dysprosium and alloys
containing these elements exhibit ferromagnetism because of the way
the electron spins within one atom interact with those of nearby atoms.
They will align themselves, creating magnetic domains forming a
permanent magnet. If a piece of iron is placed within a strong
magnetic field, the domains in line with the field will grow in size
as the domains perpendicular to the field will shrink in size.
