meaning they act like little magnets. In atoms with filled electron shells, these magnetic moments cancel each other out because each pair of electrons have moments that point in opposite directions.
Magnetism is due to the magnetic fields around magnets. The fields can be investigated by looking at the effects of the forces they exert on other magnets and magnetic materials. Electromagnets ...
