Short explanation

(Physics only) (HT only) Distinguish induced current from supplied current in electromagnetic devices. sits within Induced potential (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 physics only, HT only, induced current 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 lo47cue362 fieldmap362 coilpath362 transformerlink362, 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 Induced potential (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 electromagnets and...: Instead, identify the exact Unit 4.7 idea in Induced potential (HT only), then explain how it links to a student comparing motor and generator effects and the objective to distinguish induced current from supplied current in electromagnetic devices.
