Question

  1. A. Poles of a magnet: temporary induced magnet direction shows State that two unlike magnetic poles attract each other. because magnetic effects depend on field direction, current or changing magnetic flux.
  2. B. It says field lines travel from south to north outside the magnet. (evidence error).
  3. C. It makes AC and DC equivalent. (boundary error).
  4. D. It ignores relative motion or changing magnetic flux. (application error).

Answer

Poles of a magnet: temporary induced magnet direction shows State that two unlike magnetic poles attract each other. because magnetic effects depend on field direction, current or changing magnetic flux.

Explanation

Poles of a magnet: temporary induced magnet direction shows State that two unlike magnetic poles attract each other. 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 temporary induced magnet direction 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 loudspeaker coil moving in a magnetic field and the objective to state that two unlike magnetic poles attract each other.
