Hint: Magnetism is produced by accelerating charges.

The primary origin of magnetism lies in the fact that the electrons are revolving and spinning about the nucleus of an atom, which gives rise to a current called atomic current.

These atomic currents give rise to magnetism. The revolving and spinning nucleus of an atom is called the intrinsic spin of the electron.
