Which conclusion keeps the magnetism concept boundary clear? Context: moving-wire motor effect pole-test. Learning objective: (Physics only) (HT only) State that the generator effect is used in a dynamo to generate direct current.. Which answer is most accurate for Uses of the generator effect (HT only)?

  1. A.Uses of the generator effect (HT only): moving-wire motor effect pole-test shows (Physics only) (HT only) State that the generator effect is used in a dynamo to generate direct current. 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. (exam-command error).
  3. C.It confuses the magnetic field with an electric field. (direction error).
  4. D.It describes energy transfer but misses the force or field interaction. (cause error).
