  1. A.Uses of the generator effect (HT only): phone speaker coil power-link shows (Physics only) (HT only) Distinguish ac output from dc output using potential difference-time graphs. 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).
