Which conclusion keeps the magnetism concept boundary clear? Context: moving-wire motor effect evidence. Learning objective: (Physics only) (HT only) Describe a step-up transformer as having secondary potential difference greater than primary potential difference.. Which answer is most accurate for Transformers (HT only)?

- A.Transformers (HT only): moving-wire motor effect evidence shows (Physics only) (HT only) Describe a step-up transformer as having secondary potential difference greater than primary potential difference. 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. (exam-command error).
- C.It confuses the magnetic field with an electric field. (direction error).
- D.It describes energy transfer but misses the force or field interaction. (cause error).
