Learn about Working of an Electric Bell

The electric bell An electric bell is one of the most common examples of use of an electromagnet. Let us learn about working of an electric bell (a) In an electric bell, when you press the switch, current flows in the coil, creating an electromagnet. (b) The electromagnet then attracts the soft iron armature. The hammer attached to the armature hits the gong, causing a ring. (c) When the hammer moves towards the gong, the contact opens. The circuit is broken and the current stops flowing. (d) The coil loses its magnetism and the hammer returns to its original position, completing the circuit again. In this way, the hammer hits and lifts off from the gong repeatedly making the bell ring as long as the switch is on.
