Methods for magnetizing and demagnetizing a magnet

        METHODS FOR MAGNETIZING A MAGNET

1)RUBBING:

                 The most common method of magnetizing a magnet is rubbing.Rub the iron rod with a magnet in the direction from North to South.Repeat this process several times,the magnet will be magnetized.

2)ELECTRIC CURRENT:

                The most efficient method of magnetizing is to pass an alternating current from the U-shaped bar wounded with an insulating copper wire.

           METHODS OF DEMAGNETIZING A MAGNET

1)HEATING:

              The magnet should be placed in an east west direction and should be heated gently for demagnetizing.

2)HAMMERING:

              The magnet should be hammered in order to be demagnetized.
