Question

Make a circuit diagram to show an electromagnet
clear and shaded

Answer 1

Explanation:

A coil C of insulated copper wire is wound around a soft iron core NS and the two ends of the copper coil are connected to a battery. Thus, an electromagnet using a soft iron core. The current is switched on to energise the electromagnet and pick up the iron pieces from the scrap.

Answer 2

Answer:

On a soft iron piece an insulated copper wire is wrapped and when current is passed through the coil by using a battery and a key then iron piece behaves like a bar magnet till the current is passing through it. This type of magnet is known as an electromagnet.
