Question
- A. Poles of a magnet: split-ring motor kit evidence shows Describe the attraction and repulsion between unlike and like poles for permanent magnets. 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. (coil-core error).
- C. It makes AC and DC equivalent. (compass-response error).
- D. It ignores relative motion or changing magnetic flux. (pole-test error).
Answer
Poles of a magnet: split-ring motor kit evidence shows Describe the attraction and repulsion between unlike and like poles for permanent magnets. because magnetic effects depend on field direction, current or changing magnetic flux.
Explanation
Poles of a magnet: split-ring motor kit evidence shows Describe the attraction and repulsion between unlike and like poles for permanent magnets. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Poles of a magnet, uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The split-ring motor kit evidence detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.

Common mistake
generator-effect induction: avoid permanent and induced magnets
Treating permanent and induced magnets as interchangeable when answering about generator-effect induction.
Instead, identify the exact Unit 4.7 idea in Poles of a magnet, then explain how it links to a student comparing motor and generator effects and the objective to describe the attraction and repulsion between unlike and like poles for permanent magnets.
