Electromagnetic induction: past paper questions

Where the questions come from

• Question 31Oct/Nov 2025, paper 11Multiple choice1 markHas a diagram

  The diagram shows a magnet moving towards a coil of wire. When the magnet moves towards the coil of wire, an electromotive force (e.m.f.) is induced. Students are asked for one change that will increase the magnitude of the induced e.m.f.
