The purpose of this exercise is to observe the relationship between the magnitude of the induced EMF and the applied magnetic field
At the end of this exercise you will have:
• Used appropriate methods for measuring the induced voltage as a function of current, frequency, and angle.
• Plotted correctly drawn graphs and determined the required quantities.
Introduction
A magnetic field, which varies with time, is generated by passing a current through a short coil of wire (for this experiment, two short coils pushed together with a small gap between them). A “search coil” is placed on the axis in the centre of the two coils. Since the magnetic field is varying, an EMF is induced in the search coil. Figure 1.
