Answer:

When an electric current flows through the coils, the electromagnet creates a magnetic field which pulls the armature towards it, causing the hammer to strike the bell.

Explanation:

Electric bell is based on the principle of electromagnets. When switch is pressed, electromagnet is activated and the hammer moves and hits the gong. As the hammer moves, circuit breaks and the electromagnet is disabled. This causes the hammer to go back to initial position due to the spring and the circuit completes again. This process is continuously repeated giving the ringing sound of the bell.
