What Is an Electric Bell?

The electric bell uses the characteristics of the electromagnet to control the on and off of the current wound in the main magnetic core coil through the repeatedly closing device of the power switch to form the main magnetic circuit. The magnetic circuit of the elastic suspension magnetic core is alternately attracted and separated, so that The electric hammer on the elastic suspension magnetic core vibrates on the surface of the bell body and emits a bell. The bell can tell people the length of the work and study schedule.

[Interpretation]:

[Principle]: The magnetic effect of current: When the current is applied, the electromagnet has a current passing through it, which generates magnetism. It sucks the elastic sheet under the hammer to make the hammer strike the bell and make a sound. At the same time, the circuit is disconnected and the solenoid loses its magnetism. The small hammer was bounced back, the circuit was closed, and the bell repeated continuously, and the electric bell struck continuously.
