Explanation:
Connect the hammer and the soft iron bar.
Place the electromagnet just below the soft iron bar.
Coil a wire around the electromagnet.
Connect the wire to the battery.
Complete the circuit by placing a switch.
Working:
When you turn on the switch, the electromagnet gets magnetized.
The magnet now attracts the soft iron bar which is connected to the hammer.
This leads the hammer to hit the gong.
