Which option gives the strongest diagnostic reason? Context: primary-secondary coil comparison load-effect. Learning objective: (Physics only) (HT only) Interpret graphs of potential difference generated in a coil against time.. Which answer is most accurate for Uses of the generator effect (HT only)?

Uses of the generator effect (HT only): primary-secondary coil comparison load-effect shows (Physics only) (HT only) Interpret graphs of potential difference generated in a coil against time. because magnetic effects depend on field direction, current or changing magnetic flux.

Uses of the generator effect (HT only): primary-secondary coil comparison load-effect shows (Physics only) (HT only) Interpret graphs of potential difference generated in a coil against time. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Uses of the generator effect (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The primary-secondary coil comparison load-effect detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
