Draw a labelled diagram explain the working of an electric bell?

The electric bell hasa coil of wire wound around a piece of iron which it acts like an electromagnet. An iron strip with a hammer is kept close to the electromagnet. There is a contact screw near the iron strip. When the srip is in contact with the screw, current flows through the coil and becomes an electromagnet. It pulls the iron strip and the hammer at the end of the strip, and hits the gong of the bell and produces sound. When the electromagnet pulls the iron strip, it also breaks the circuit and the iron strip comes back to the original position and the process repeats and the bell rings.

Hello Aman!!!  : )
Here Is The Answer:

An electric bell consists of an iron core, on which is wound a wire as a coil. One end of the coil is connected to one terminal of a battery, and the other end to a steel rod that acts like a spring for the hammer touching the screw contact. The other terminal of the battery is connected to the screw contact with a switch in the middle.
Electric current flows through the coil when the switch is ON, and the iron core acts as an electromagnet. The iron core attracts the hammer towards it. The hammer hits the bell and produces a sound. The circuit breaks at the screw contact when the hammer moves towards the iron core. At this point, the iron core ceases to be an electromagnet. The hammer is pulled back to its original position due to the spring action of the steel rod, and then touches the contact again to complete the circuit. The circuit is completed and current flows through the coil again, and the hammer strikes the bell again. The process repeats itself and you hear a ringing sound since the hammer keeps hitting the bell, until the switch is released.
