Which explanation best links the observation to the physics? Context: laboratory bar magnet direction. Learning objective: (Physics only) (HT only) Recognise that knowledge of laminations and eddy currents in the core is not required.. Which answer is most accurate for Transformers (HT only)?

Transformers (HT only): laboratory bar magnet direction shows (Physics only) (HT only) Recognise that knowledge of laminations and eddy currents in the core is not required. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): laboratory bar magnet direction shows (Physics only) (HT only) Recognise that knowledge of laminations and eddy currents in the core is not required. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Transformers (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The laboratory bar magnet direction detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
