When you switch on the current through the circuit, due to the magnetic field formed by the current, the soft iron core (of the electromagnet) gets magnetized. Since iron gets attracted to a magnet, the electromagnet attracts it. The hammer fixed at the end of the iron strip thus hits the gong and a sound is produced.
