How to electric bell represent magnetic energy.

An electric bell has an iron hammer around which a wire is wound. When the button is pressed, current passes through the circuit and the wire turns into a temporary electromagnet. The hammer is attracted towards the bell, and it strikes the gong to produced sound. When the shift in arrangement occurs due to the movement of the hammer, the current is disconnected automatically. The magnetic property of the wire is lost and it comes back to its original position through a spring. Once again, the circuit gets completed. This process is repeated in quick succession. The hammer strikes the gong every time the circuit is completed. This is how an electric bell works.
