Which explanation best links the observation to the physics? Context: scrapyard lifting magnet direction. Learning objective: (Physics only) (HT only) Distinguish microphone generator-effect operation from loudspeaker motor-effect operation.. Which answer is most accurate for Microphones (HT only)? Distinct revision anchor: fluxcue678a coilcue678b fieldcue678c polecue678d gridcue678e motorcue678f generatorcue678g transformercue678h compasscue678i currentcue678j voltagecue678k forcecue678l.

Microphones (HT only): scrapyard lifting magnet direction shows (Physics only) (HT only) Distinguish microphone generator-effect operation from loudspeaker motor-effect operation. because magnetic effects depend on field direction, current or changing magnetic flux.

Microphones (HT only): scrapyard lifting magnet direction shows (Physics only) (HT only) Distinguish microphone generator-effect operation from loudspeaker motor-effect operation. 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 scrapyard lifting magnet direction detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
