Answer 2

hi,
here is your answer.

WORKING OF A ELECTRIC BELL

when the BELL is switched on, the point p and q gets joined. This completes circuit.

#1
when the current flows through the circuit the abcd coil turns into electromagnet, it become a a strong electromagnet as there is a iron rod in side the coil.

#2
the metal attracts the metal arm xy.

#3
the arm with which hammer (h) is attatchment hits the gong (g) and makes sound.

#4
now as the arm is out of the position the circuit breaks at point (e). as the circuit breaks the current stop flowing through the circuit.
