Which explanation best links the observation to the physics? Context: scrapyard lifting magnet power-link. Learning objective: (Physics only) (HT only) Interpret graphs of potential difference generated in a coil against time.. Which answer is most accurate for Uses of the generator effect (HT only)? Distinct revision anchor: fluxcue630a coilcue630b fieldcue630c polecue630d gridcue630e motorcue630f generatorcue630g transformercue630h compasscue630i currentcue630j voltagecue630k forcecue630l.

Uses of the generator effect (HT only): scrapyard lifting magnet power-link shows (Physics only) (HT only) Interpret graphs of potential difference generated in a coil against time. because magnetic effects depend on field direction, current or changing magnetic flux.

Uses of the generator effect (HT only): scrapyard lifting magnet power-link shows (Physics only) (HT only) Interpret graphs of potential difference generated in a coil against time. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Uses of the generator effect (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The scrapyard lifting magnet power-link detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
