Electrifying a permanent magnet

    What happens, and why? (This isn't homework, just curiosity.)

    To be more precise, what would happen to the magnetic field of the magnet if we passed a current through it (assuming it is conductive). Will the current disrupt the magnetic domains? Will the magnetization disappear?

    It may surprise you to know that one way to produce a permenant magnet is to pass high current through a conductive metal. The direction of the current will determine the direction of the field.
