Which answer avoids the common misconception in this topic? Context: coil-and-galvanometer induction exam-command. Learning objective: (Physics only) (HT only) Link movement of a coil in a magnetic field to induced potential difference in a microphone.. Which answer is most accurate for Microphones (HT only)?

Microphones (HT only): coil-and-galvanometer induction exam-command shows (Physics only) (HT only) Link movement of a coil in a magnetic field to induced potential difference in a microphone. because magnetic effects depend on field direction, current or changing magnetic flux.

Microphones (HT only): coil-and-galvanometer induction exam-command shows (Physics only) (HT only) Link movement of a coil in a magnetic field to induced potential difference in a microphone. 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 coil-and-galvanometer induction exam-command detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
