The striker of the electric bell moves due to attractive force of the electromagnet.

Say True or False.

Write the following steps in sequential order can be used to explain the working of an electric bell?

(a) When current passes through the coil, it behaves like a magnet and attracts (pulls) the iron strip.

(b) No more does the coil behave as an electromagnet and the attraction between the coil and the iron strip is lost. Because of this the iron strip gets back to its original position and touches the screw.

(d) When the iron strip is pulled towards the coil, it loses contact with the screw and the circuit becomes open circuit.

(e) Once again the circuit is closed, and the above process is repeated
