Question Image

An electric bell consists of an electromagnet, switch, iron strip, contact screw, hammer and a gong.

  • When the switch is ON, the circuit gets closed and an electric current is passed through the circuit.
  • Due to an electric current, the coil of iron starts acting as an electromagnet.
  • This electromagnet pulls the iron strip.
  •  In the process, the hammer at the end of the strip strikes the gong of the bell to produce a sound.

Therefore, the correct statement would be:

When electric current flows through the electric circuit of an electric bell, the hammer strikes the gong to create the sound.
