- A.Poles of a magnet: wind-turbine generator cause shows State that a permanent magnet produces its own magnetic field. because magnetic effects depend on field direction, current or changing magnetic flux.
- B.It says field lines travel from south to north outside the magnet. (voltage-change error).
- C.It makes AC and DC equivalent. (force-link error).
- D.It ignores relative motion or changing magnetic flux. (turns-ratio error).
