2. (a) Connect a long PVC-coated copper wire in series with a rheostat, an ammeter and a signal generator
(b) Switch on the signal generator. Set the output voltage to 0-6 V of frequency 5 kHz in sine wave
(c) Place the search coil near one side of wire. Adjust the time base of the CRO until a waveform is show on the CRO screen of the induced e.m.f. shown on the CRO screen is maximum.
