Method of Making magnet:

There are two types of making magnets.

Single Touch Method:

a. In this method a bar magnet is rubbed on a hard steel bar.

b. The magnet is kept in inclined position. Position and its direction should be from south to north.

c. On reaching the north pole, the bar magnet is lifted and the process is repeated again and again.

Electric Method:

a. In this method insulated copper wire is wound around a u-shaped steel bar.

b. The two ends of the wire are linked with the battery and strong current is passed by the coil for few seconds.
