In this activity, you will measure the induced e.m.f. when a coil is placed in a varying magnetic field. You will use home-made coil frame to vary the shape and area. You will also investigate the induced e.m.f. due to linearly varying magnetic field.
In Experiment 1, you will compare the current in the solenoid and the induced e.m.f. in a coil with a CRO. You will then measure the induced e.m.f. for coils of different number of turns.
Experiment 2 is similar to investigating the number of turns of coil in Experiment 1, except that you will use coils of different shapes but with the same area, and then coils of the same shape but with different areas.
In Experiment 3, you will set the signal generator to give sawtooth waveform (linearly varying) and study the corresponding induced e.m.f.
