- A.Loudspeakers (physics only) (HT only): split-ring motor kit turns-ratio shows (Physics only) (HT only) Explain how a moving-coil loudspeaker works. 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. (coil-core error).
- C.It makes AC and DC equivalent. (compass-response error).
- D.It ignores relative motion or changing magnetic flux. (pole-test error).
