Book Free DemoOrder the procedure to show the working of an electric bell.
Answer variants:
Thus, the coil becomes an electromagnet and pulls the iron strip such that the hammer strikes the gong of the bell.
Thus, the coil is no longer an electromagnet and hence, it does not attract the iron strip.
An iron piece is wounded with a coil of wire which acts as an electromagnet.
This process is repeated again and again and makes the bell ring.
At the end of an iron strip, a hammer is placed.
The circuit breaks and the current flow is stopped when the coil pulls the iron strip.
A contact screw is placed near the iron strip so that current flows through it.
Again, the iron strip touches the contact screw when it reaches its original position, thus completing the circuit.
