Which option gives the strongest diagnostic reason? Context: loudspeaker cone test cause. Learning objective: (Physics only) (HT only) Explain how the effect of an alternating current in one coil inducing a current in another is used in transformers.. Which answer is most accurate for Transformers (HT only)?

Transformers (HT only): loudspeaker cone test cause shows (Physics only) (HT only) Explain how the effect of an alternating current in one coil inducing a current in another is used in transformers. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): loudspeaker cone test cause shows (Physics only) (HT only) Explain how the effect of an alternating current in one coil inducing a current in another is used in transformers. 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 loudspeaker cone test cause detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
