Select the statement that would earn credit in an AQA GCSE Physics answer. Context: step-up transformer demonstration AC-output. Learning objective: (Physics only) (HT only) Describe how a potential difference is induced across a conductor when the conductor moves relative to a magnetic field.. Which answer is most accurate for Induced potential (HT only)?

- A.Induced potential (HT only): step-up transformer demonstration AC-output shows (Physics only) (HT only) Describe how a potential difference is induced across a conductor when the conductor moves relative to a magnetic field. 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. (force-link error).
- C.It confuses the magnetic field with an electric field. (turns-ratio error).
- D.It describes energy transfer but misses the force or field interaction. (AC-output error).
