Which option gives the strongest diagnostic reason? Context: phone speaker coil pole-test. Learning objective: (Physics only) (HT only) Distinguish induced current from supplied current in electromagnetic devices.. Which answer is most accurate for Induced potential (HT only)?

Induced potential (HT only): phone speaker coil pole-test shows (Physics only) (HT only) Distinguish induced current from supplied current in electromagnetic devices. because magnetic effects depend on field direction, current or changing magnetic flux.

Induced potential (HT only): phone speaker coil pole-test shows (Physics only) (HT only) Distinguish induced current from supplied current in electromagnetic devices. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Induced potential (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The phone speaker coil pole-test detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
