Driving question : How does the magnetic field behave in a coil through which current is flowing?
Students are introduced to a semi-automated method of measurement using a positioning device. They also explore the strength of the magnetic field around and inside a coil, which requires them to position the equipment accurately. They then plot the distance against the magnetic flux on a graph.
Topic: Electromagnetic induction,
Concepts: Magnetic field, Magnetic flux,
