The magnetism of a permanent magnet results from the magnetism of a permanent magnet results from interactions with earth's magnetic field the magnetic moments of nuclei in the material making up the magnet macroscopic electric current through the magnet the magnetic moments of electrons in the material making up the magnet

Magnetic moments of electrons in the material making up magnet

Explanation:

The magnetism in a permanent magnet results from magnetic moments of electrons in the material making up the magnet. Each atom(circulating charges) the material is a tiny bar of magnet. Now because of quantum mechanical effect the bulk of these tiny magnets tend to line up in single direction forming domains. Thus, magnetizing the whole material.
