Which conclusion keeps the magnetism concept boundary clear? Context: iron-filings field pattern application. Learning objective: (Physics only) (HT only) Identify Vp x Ip as power input and Vs x Is as power output.. Which answer is most accurate for Transformers (HT only)?

Transformers (HT only): iron-filings field pattern application shows (Physics only) (HT only) Identify Vp x Ip as power input and Vs x Is as power output. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): iron-filings field pattern application shows (Physics only) (HT only) Identify Vp x Ip as power input and Vs x Is as power output. 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 iron-filings field pattern application detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
