Which conclusion keeps the magnetism concept boundary clear? Context: classroom plotting compass exam-command. Learning objective: (Physics only) (HT only) Explain how a moving-coil microphone works.. Which answer is most accurate for Microphones (HT only)? Distinct revision anchor: fluxcue661a coilcue661b fieldcue661c polecue661d gridcue661e motorcue661f generatorcue661g transformercue661h compasscue661i currentcue661j voltagecue661k forcecue661l.

Microphones (HT only): classroom plotting compass exam-command shows (Physics only) (HT only) Explain how a moving-coil microphone works. because magnetic effects depend on field direction, current or changing magnetic flux.

Microphones (HT only): classroom plotting compass exam-command shows (Physics only) (HT only) Explain how a moving-coil microphone works. 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 classroom plotting compass exam-command detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
