Which conclusion keeps the magnetism concept boundary clear? Context: moving-wire motor effect power-link. Learning objective: (Physics only) (HT only) State that microphones use the generator effect.. Which answer is most accurate for Microphones (HT only)?

Microphones (HT only): moving-wire motor effect power-link shows (Physics only) (HT only) State that microphones use the generator effect. because magnetic effects depend on field direction, current or changing magnetic flux.

Microphones (HT only): moving-wire motor effect power-link shows (Physics only) (HT only) State that microphones use the generator effect. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Microphones (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The moving-wire motor effect power-link detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
