Answer 2

If a soft iron bar is taken and several turns of insulated copper wire are wound over it, then on passing electric current through the wire, we find that the iron bar becomes a magnet.

As long as the current is flowing through the wire, the iron bar remains a magnet. On stopping the current, the bar loses its magnetism

The temporary magnet produced by electricity is called an electromagnet.

Uses -
