Which conclusion keeps the magnetism concept boundary clear? Context: classroom plotting compass voltage-change. Learning objective: (HT only) Recognise that the motor-effect equation is given on the Physics equation sheet.. Which answer is most accurate for Fleming's left-hand rule (HT only)?

Fleming's left-hand rule (HT only): classroom plotting compass voltage-change shows (HT only) Recognise that the motor-effect equation is given on the Physics equation sheet. because magnetic effects depend on field direction, current or changing magnetic flux.

Fleming's left-hand rule (HT only): classroom plotting compass voltage-change shows (HT only) Recognise that the motor-effect equation is given on the Physics equation sheet. 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 classroom plotting compass voltage-change detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
