This Circuits and Magnetic Fields activity also includes:
Have your class use compasses to try to find the magnetic field around an electric current. Groups use the same technique to visualize magnetic fields as they did in the second activity in the series, but this time, the field is created by an electric current. Through the activity, pupils become aware of the three-dimensional magnetic field.
