3 Ways to Magnetize Metal

 · Test the magnetism of the metal. Place the piece of metal on top of some paperclips and see if they stick. If the paperclips stick, the metal has been magnetized. If the paperclips don''t stick, try striking the end of the metal a few more times. If you find this method doesn''t work, the amount of iron in the piece of metal might be too small.
