Question
- A. Induced potential (HT only): temporary induced magnet coil-core shows (Physics only) (HT only) Explain that the original change may be the movement of the conductor or the change in magnetic field. because magnetic effects depend on field direction, current or changing magnetic flux.
- B. It says field lines travel from south to north outside the magnet. (evidence error).
- C. It makes AC and DC equivalent. (boundary error).
- D. It ignores relative motion or changing magnetic flux. (application error).
Answer
Induced potential (HT only): temporary induced magnet coil-core shows (Physics only) (HT only) Explain that the original change may be the movement of the conductor or the change in magnetic field. because magnetic effects depend on field direction, current or changing magnetic flux.
Explanation
Induced potential (HT only): temporary induced magnet coil-core shows (Physics only) (HT only) Explain that the original change may be the movement of the conductor or the change in magnetic field. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Induced potential (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The temporary induced magnet coil-core detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.

Common mistake
National Grid transformer reasoning: avoid magnetic field...
Treating magnetic field direction and force direction as interchangeable when answering about National Grid transformer reasoning.
Instead, identify the exact Unit 4.7 idea in Induced potential (HT only), then explain how it links to a dynamo producing a DC output trace and the objective to explain that the original change may be the movement of the conductor or the change in magnetic field.
