Which explanation best links the observation to the physics? Context: scrapyard lifting magnet voltage-change. Learning objective: (HT only) Apply MS 3b and MS 3c when using the motor-effect equation.. Which answer is most accurate for Fleming's left-hand rule (HT only)? Distinct revision anchor: fluxcue438a coilcue438b fieldcue438c polecue438d gridcue438e motorcue438f generatorcue438g transformercue438h compasscue438i currentcue438j voltagecue438k forcecue438l.

Fleming's left-hand rule (HT only): scrapyard lifting magnet voltage-change shows (HT only) Apply MS 3b and MS 3c when using the motor-effect equation. because magnetic effects depend on field direction, current or changing magnetic flux.

Fleming's left-hand rule (HT only): scrapyard lifting magnet voltage-change shows (HT only) Apply MS 3b and MS 3c when using the motor-effect equation. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Fleming's left-hand rule (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The scrapyard lifting magnet voltage-change detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
