24 Magnetic Fields

This page covers the magnetic fields section of the course.  It is worth realising that the iGCSE does not cover all the ideas that AQA 1-9 GCSE covers for this part of the course. Hence, it is worth going over things like FBI from formulae perspective unless you teacher did some extra ideas.

Electric motor quiz

Label an electric motor


Circuit construction kit – PhET

Build circuits with capacitors and inductors


Amazing... Magic.... Induced Magnetism

This a little video about induced magnetism and how it works. The domains line up and the field is passed through the iron domains so they line up.
