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:...

Produced by the Institute of Physics, these discussions and demonstrations show that in a generator, motion of a conductor in a magnetic field induces an electromotive force (emf). In a transformer, it is the changing field that induces an emf in a fixed conductor.
