  1. A.Transformers (HT only): phone speaker coil measurement shows (Physics only) (HT only) Calculate the current drawn from the input supply to provide a particular power output. because magnetic effects depend on field direction, current or changing magnetic flux.
  2. B.It treats a permanent magnet as if it only works when current flows. (prediction error).
  3. C.It confuses the magnetic field with an electric field. (comparison error).
  4. D.It describes energy transfer but misses the force or field interaction. (safety error).
