Which explanation best links the observation to the physics? Context: scrapyard lifting magnet 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: fluxcue510a coilcue510b fieldcue510c polecue510d gridcue510e motorcue510f generatorcue510g transformercue510h compasscue510i currentcue510j voltagecue510k forcecue510l.

Loudspeakers (physics only) (HT only): scrapyard lifting magnet 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): scrapyard lifting magnet 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 scrapyard lifting magnet AC-output detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
