Question

How to increase the strength of an electromagnet

Answer 1

Putting a piece of iron or steel inside the coil makes the magnet strong enough to attract objects. The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.

(1) By Increasing the current flow the coil

(2) Increasing the number of turns in the coils

(3) Placing an 'iron core' through the coil of the electromagnet.
