The magnetic field of a magnet is actually generated by the alignment of electrons within the
atomic structure of the magnetic material. All objects contain atoms, and these atoms contain
electrons that move around in orbits with a certain spin. The movement of any electron in this
manner creates a tiny magnetic field. However, most electrons in atoms exist in pairs. The two
electrons in a pair always spin in opposite directions, with the result that the magnetic fields
cancel each other out, and no magnetic field is created from the object itself.
Atoms of magnetic materials, on the other hand, contain unpaired electrons with the same spin
that aren't canceled out. If a material has enough unpaired electrons with the same spin--such as
the four unpaired electrons in an atom of Fe (iron)--and doesn't contain any unpaired electrons
with opposite spin, the net movement of electrons in one direction will create a magnetic field.
