Electric bell

Electric bell

• When the switch is closed, current flows through the circuit and the core become magnetized
• The iron armature is attracted towards the magnetized core causing hammer to hit the gong and produce sound but this breaks the contact and the circuit.
• When the circuit is broken, the iron core loses magnetism releasing the armature to be returned to the contact by the spring.
• Again the circuit is completed and the process repeats, the hammer making repeated sound.
