The pushing of the doorbell closes an electric circuit. Then electric current flows through an electromagnet, and the doorbell rings. How are electromagnets used in a doorbell?
When the electrical current flowing through the voice coil changes direction, the coil's polar orientation reverses. The voice coil is a basic electromagnet. If you've read How Electromagnets Work, then you know that an electromagnet is a coil of wire, usually wrapped around a piece of magnetic metal, such as iron.he field acts just like the magnetic field around a permanent magnet: It has a polar orientation -- a north end and and a south end -- and it is attracted to iron objects. But unlike a permanent magnet, in an electromagnet you can alter the orientation of the poles.
