- A.Loudspeakers (physics only) (HT only): wind-turbine generator turns-ratio shows (Physics only) (HT only) Describe how variations in current in an electrical circuit are converted into pressure variations in sound waves. 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).
