But when you introduce an external magnetic field, each domain aligns with that field and produces their own magnetic field. Even after you remove the external field, all of the domains reinforce each other and the material maintains its magnetic field. This creates a property called magnetic hysteresis, which you can read all about here.

Anything that is magnetic, like a bar magnet or a loop of electric current, has a magnetic moment. A magnetic moment is a vector quantity, with a magnitude and a direction. An electron has an electron magnetic dipole moment, generated by the electron's intrinsic spin property, making it an electric charge in motion.
