Which explanation best links the observation to the physics? Context: laboratory bar magnet pole-test. Learning objective: (Physics only) (HT only) State that the generator effect is used in a dynamo to generate direct current.. Which answer is most accurate for Uses of the generator effect (HT only)? Distinct revision anchor: fluxcue600a coilcue600b fieldcue600c polecue600d gridcue600e motorcue600f generatorcue600g transformercue600h compasscue600i currentcue600j voltagecue600k forcecue600l.

Uses of the generator effect (HT only): laboratory bar magnet pole-test shows (Physics only) (HT only) State that the generator effect is used in a dynamo to generate direct current. because magnetic effects depend on field direction, current or changing magnetic flux.

Uses of the generator effect (HT only): laboratory bar magnet pole-test shows (Physics only) (HT only) State that the generator effect is used in a dynamo to generate direct current. 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 laboratory bar magnet pole-test detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
