Which explanation best links the observation to the physics? Context: scrapyard lifting magnet evidence. Learning objective: (Physics only) (HT only) Recall and apply the transformer equation Vp / Vs = np / ns.. Which answer is most accurate for Transformers (HT only)?

Transformers (HT only): scrapyard lifting magnet evidence shows (Physics only) (HT only) Recall and apply the transformer equation Vp / Vs = np / ns. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): scrapyard lifting magnet evidence shows (Physics only) (HT only) Recall and apply the transformer equation Vp / Vs = np / ns. 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 scrapyard lifting magnet evidence detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
