Question

State the two methods of making a magnet.

Answer 1

The two methods of making a magnet are:

Induction method:

1. This method involves placing the magnetic material (soft iron) close to a strong magnet without touching it.
2. The soft iron bar becomes an induced magnet with the end nearer the magnet having opposite polarity to that of the magnet.

Electrical method:

1. In this method, an electric current is passed through a coil wrapped around the soft iron bar.
2. On the passage of current, the bar behaves as a magnet.
3. Higher the magnitude of the electric current passed, the higher the magnetic strength of the bar and vice versa.
