Answer:
Rub the metal with the magnet in the opposite direction that you used to magnetize it. Continue rubbing until the metal no longer attracts other metal. Wait out the magnetization, if desired. It is not necessary to demagnetize metal if time is not an issue because metal loses it magnetism over time.
