This exam focus covers Exam Focus: Electromagnetic Induction within Electromagnetic Induction for GCSE Physics. Revise Electromagnetic Induction in Magnetism for GCSE Physics with 18 exam-style questions and 12 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 12 of 14 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.
🎯 Exam Focus: Electromagnetic Induction
How this topic appears in exams:
- Describe induction (2-3 marks): Explain why pushing a magnet into a coil induces a current; what happens when it stops
- Factors affecting EMF (3 marks): State and explain three ways to increase the induced EMF
- Generator description (3-4 marks): Describe how an AC generator works with reference to coil, magnet, slip rings
- Graph interpretation (2-3 marks): Interpret the AC output graph from a generator; explain why EMF is zero at certain points
- Lenz's law application (2-3 marks): Explain why the induced current opposes the change that caused it
