         ** Magnetic fields are created by moving electric charges. Electrons are subatomic particles that carry a charge and they are in constant motion within an atom.

In most atoms the magnetic fields created by the electrons cancel each other out. This is the case with copper. Iron happens to have an arrangement of electrons in which some of the magnetic fields is not canceled and this is what gives rise to the magnetic properties of iron.
