What is the function of an electromagnet in an electric doorbell?
The electromagnet in a doorbell attracts the clapper, which hits the bell and makes it ring. An electric motor is a device that uses an electromagnet to change electrical energy to kinetic energy. When current flows through the motor, the electromagnet rotates, causing a shaft to rotate as well.
When you press a doorbell button, you complete an electrical circuit that allows household electricity to flow through the doorbell’s internal electromagnet. The magnetic field generated by the electromagnet is then used to power a mechanism that creates the doorbell sound. Doorbells are low-voltage devices.
