how is a magnet made?
Asked by thamby | 2nd Aug, 2010, 12:00: AM
Magnets can be made by exposing a piece of metal to a magnetic field. This can be done by running a magnet along the length of the metal. The molecules inside the metal rearrange themselves so that they line up in a north-south pattern. Once this happens, the metal is polarized and magnetized as a permanent magnet. It willl not lose its magnetic field over time.
