Select the statement that would earn credit in an AQA GCSE Physics answer. Context: bench-top compass mapping AC-output. Learning objective: (Physics only) (HT only) Explain how headphones use the motor effect to produce sound.. Which answer is most accurate for Loudspeakers (physics only) (HT only)? Distinct revision anchor: fluxcue509a coilcue509b fieldcue509c polecue509d gridcue509e motorcue509f generatorcue509g transformercue509h compasscue509i currentcue509j voltagecue509k forcecue509l.

Loudspeakers (physics only) (HT only): bench-top compass mapping AC-output shows (Physics only) (HT only) Explain how headphones use the motor effect to produce sound. because magnetic effects depend on field direction, current or changing magnetic flux.

Loudspeakers (physics only) (HT only): bench-top compass mapping AC-output shows (Physics only) (HT only) Explain how headphones use the motor effect to produce sound. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Loudspeakers (physics only) (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The bench-top compass mapping AC-output detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
