(Physics only) (HT only) Describe a step-up transformer as having secondary potential difference greater than primary potential difference.

(Physics only) (HT only) Describe a step-up transformer as having secondary potential difference greater than primary potential difference. sits within Transformers (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, transformer, potential difference 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 lo47cue388 fieldmap388 coilpath388 transformerlink388, which separates this learning objective from neighbouring transformer, motor-effect and magnetic-field objectives while preserving the official wording.
