Question

Why is an electromagnet a temporary magnet?

Answer 1

An electromagnet is a temporary magnet. It is made by winding a coil of insulated wire round a soft iron core. When a current is passed through the coil, the magnetic field produced by the current magnetises the soft iron core. The soft iron core loses all the magnetism when the current is switched off.

Step-by-step explanation:

yes

Answer 2

The magnetic field generated by the electromagnet only appears when there is an electrical current applied to it. The magnet field will disappear once the electrical current has left.
