An electric bell has an electromagnet fitted in its circuit. One or two electromagnets made of wires coiled on iron pieces are fixed on the bell case. When the bell switch is pressed, the current flows through these coils, and these become magnets. These magnets attract a metal strip, which has a hammer attached to its end near the gong of the bell. The metal strip moves fast towards the electromagnet, and the hammer strikes the gong. At the same time, with the movement of the metal strip from its position, the electric circuit breaks, the magnet stops working, and the strip moves back to its original position.
