Episode 414: Electromagnetic Induction

In these activities, from the Institute of Physics, students investigate electromagnetic induction. The learning episode develops a picture of induction as the cutting of lines of flux by a conductor, which leads to an induced electromotive force (emf) or current. The activities in this learning episode include:

  • investigating induction using a wire, magnet and meter
  • demonstrating induction effects
  • flux and flux linkage
  • questions on flux linkage
  • questions on induced emfs
  • demonstrating eddy currents
  • questions on eddy currents and Lenz's law
