Many students struggle to predict if a potential difference will be induced in a wire moving in a magnetic field

  • Electromagnetic Induction (16-19)

    Students will already have ideas about electromagnetic induction. In this resource, your task is to develop a picture of induction which involves cutting the lines of flux by a conductor that leads to an induced EMF or current.

  • Cutting a magnetic field with a wire (11-16)

    Students should previously have inserted a magnet into a coil and measured the e.m.f. generated. This is a simpler version showing first of all only one coil (or loop) of wire.
