Which conclusion keeps the magnetism concept boundary clear? Context: classroom plotting compass application. Learning objective: (Physics only) (HT only) Recall and apply the equation Vp x Ip = Vs x Is for a 100 percent efficient transformer.. Which answer is most accurate for Transformers (HT only)?

- A.Transformers (HT only): classroom plotting compass application shows (Physics only) (HT only) Recall and apply the equation Vp x Ip = Vs x Is for a 100 percent efficient transformer. 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. (energy-transfer error).
- C.It confuses the magnetic field with an electric field. (field-shape error).
- D.It describes energy transfer but misses the force or field interaction. (current-change error).
