Which answer avoids the common misconception in this topic? Context: coil-and-galvanometer induction cause. Learning objective: (Physics only) (HT only) State that the ratio of the potential differences across the primary and secondary coils depends on the ratio of the number of turns on each coil.. Which answer is most accurate for Transformers (HT only)?

Transformers (HT only): coil-and-galvanometer induction cause shows (Physics only) (HT only) State that the ratio of the potential differences across the primary and secondary coils depends on the ratio of the number of turns on each coil. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): coil-and-galvanometer induction cause shows (Physics only) (HT only) State that the ratio of the potential differences across the primary and secondary coils depends on the ratio of the number of turns on each coil. 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 coil-and-galvanometer induction cause detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
