Detailed Solution

Electric bell works on the principle of electromagnetism.

It consists of an electromagnet, switch, iron strip, contact screw, hammer and a gong.

When the switch is ON, the circuit gets closed and an electric current is passed through the circuit.
Due to the electric current, the coil of iron starts acting as an electromagnet.
This electromagnet pulls the iron strip.

Therefore, we can say that when electric current flows through the electric bell, the iron strip is attracted towards the electromagnet.
