Electromagnetism, Induction and Transformers

What the resources cover

The unit follows the topic from magnets to power lines. The mind map Electromagnetism starts with magnetic fields and field lines. Section 6- Magnetism and Electromagnetism is a wider map linking magnets, the motor effect, electric motors, electromagnetic induction and transformers. The Transformers map explains why a transformer needs alternating current to create a changing magnetic field.

Where to start

1. Begin with the Electromagnetism mind map to see the whole topic.
2. Try the 0654 Simple Phenomena of Magnetism Quiz for magnets and the choice between iron and steel rods.
3. Move to the flashcards on electric motors, generators and power transmission, which cover the split-ring commutator, carbon brushes and the torque equation.
4. Finish with the IGCSE Electromagnetism Quiz, which asks which device works because of an induced e.m.f.

Using quizzes and maps together

Read a map first, then take a quiz on the same idea. When a question catches you out, go back to the matching branch of the map and say it aloud in your own words. Flashcards then help you remember definitions and equations.

If you need circuit basics first, the Year 9 Electricity deck asks what current is, its unit and the equation linking charge, current and time. The IB Physics Topics 5.2 and 5.3 deck covers e.m.f. and p.d. For higher-level work, the quiz on electric fields and forces and the Capacitors mind map extend the ideas.

Where it fits

This unit sits in the Electricity and Magnetism strand of Physics. Resources mention GCSE, IGCSE, A-level, IB, Leaving Certificate and SACE courses, so you can pick the ones that match your own.
