Short explanation

(Physics only) (HT only) State that the generator effect is used in an alternator to generate alternating current. sits within Uses of the generator effect (HT only) in AQA GCSE Physics Unit 4.7 Magnetism and electromagnetism. A strong explanation names the exact magnetic context, then links the observation to field direction, current, force, coil turns, induced potential difference or transformer power as appropriate. For this objective, revise the keywords alternator, alternating current, physics only, HT only, generator effect and use them as evidence rather than as isolated definitions. Keep the boundary precise: permanent magnets are not induced magnets, motors use current to produce force or motion, generators use motion or changing magnetic fields to induce a potential difference, and transformers compare primary and secondary coils. The distinctive exam cue is lo47cue373 fieldmap373 coilpath373 transformerlink373, which separates this learning objective from neighbouring transformer, motor-effect and magnetic-field objectives while preserving the official wording.

Why it matters

This objective helps connect Uses of the generator effect (HT only) to exam-style questions, flashcards, and revision notes for Induced potential, transformers and the National Grid (physics only) (HT only).

Common mistakes

1 linked
  • National Grid transformer reasoning: avoid motors and generators: Instead, identify the exact Unit 4.7 idea in Uses of the generator effect (HT only), then explain how it links to a calculation using primary and secondary coils and the objective to state that the generator effect is used in an alternator to generate alternating current.
