Short explanation

(HT only) Use motor-effect reasoning to explain the operation of a simple electric motor. sits within Electric motors (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 HT only, electric motor 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 lo47cue353 fieldmap353 coilpath353 transformerlink353, which separates this learning objective from neighbouring transformer, motor-effect and magnetic-field objectives while preserving the official wording.

  • motor-effect force direction: avoid motors and generators: Instead, identify the exact Unit 4.7 idea in Electric motors (HT only), then explain how it links to a step-up transformer on the National Grid and the objective to use motor-effect reasoning to explain the operation of a simple electric motor.
