Select the statement that would earn credit in an AQA GCSE Physics answer. Context: bench-top compass mapping load-effect. Learning objective: (Physics only) (HT only) Explain how the generator effect is used in an alternator to generate ac.. Which answer is most accurate for Uses of the generator effect (HT only)?

- A.Uses of the generator effect (HT only): bench-top compass mapping load-effect shows (Physics only) (HT only) Explain how the generator effect is used in an alternator to generate ac. because magnetic effects depend on field direction, current or changing magnetic flux.
- B.It treats a permanent magnet as if it only works when current flows. (boundary error).
- C.It confuses the magnetic field with an electric field. (application error).
- D.It describes energy transfer but misses the force or field interaction. (measurement error).
