How to Demagnetize a Magnet

To demagnetize metal using this method, place the object on a hard surface and hit it with a hammer. The impact will cause the magnetism to dissipate, thus demagnetizing the metal. Make sure you hit the object squarely, or you may not be successful in removing the magnetism. Also, keep in mind that this method can be dangerous.
