In a classic electric bell (not the modern day electronic ones), an electromagnet was fitted such that when the switch was turned on, it created a magnetic field due to which a nearby magnetic hammer would be attracted to it and strike it thereby creating the sound of the bell. When the switch is turned off, the hammer goes back to it's original position due to springs fitted.
