Answer:
An electric bell is a mechanical or electronic bell that functions by means of an electromagnet.....
An electric bell contains an electromagnet, consisting of coils of insulated wire wound round iron rods. When an electric current flows through the coils, the rods become magnetic and attract a piece of iron attached to a clapper. The clapper hits the bell and makes it ring.
