Which option gives the strongest diagnostic reason? Context: loudspeaker cone test load-effect. Learning objective: (Physics only) (HT only) Explain how the generator effect is used in a dynamo to generate dc.. Which answer is most accurate for Uses of the generator effect (HT only)?

Uses of the generator effect (HT only): loudspeaker cone test load-effect shows (Physics only) (HT only) Explain how the generator effect is used in a dynamo to generate dc. because magnetic effects depend on field direction, current or changing magnetic flux.

Uses of the generator effect (HT only): loudspeaker cone test load-effect shows (Physics only) (HT only) Explain how the generator effect is used in a dynamo to generate dc. 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 loudspeaker cone test load-effect detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
