Question

why do we use nichromeof an electric bell​

Answer 1

Explanation:

The main purpose of using electromagnets in electric bells is to make and break the electric circuit in an electric bell. When the switch is on, the electric current flows through the circuit, allowing the electromagnet to pull the iron strip, which makes the hammer, hit the gong to ring the bell.

Answer 2

Answer:

The electric bells use electromagnets. The electromagnet in an electric bell will generally create a magnetic field that attracts the iron clapper towards it. The clapper generally strikes the gong. When the clapper generally strikes the gong the current stops flowing through the circuit.
