Explain electric bell in short sentences?

An electric bell is a type of bell mechanism that operates with the use of a supply of electricity and some form of electromagnet.
The basic concept of an electric bell involves creating a mechanism that includes a bell or some type of gong as part of the design. In addition to the bell, the device is equipped with a metal arm that is configured with a ball on one end. This ball, known as a clapper, is used to strike the bell repeatedly as a means of producing the series of sounds of the bell clamoring. With an electric bell, the action of the arm and clapper are controlled with the use of wiring and springs that trigger the ringing action, and also bring the action to an end once the cycle is completed.
