Which answer avoids the common misconception in this topic? Context: wind-turbine generator power-link. Learning objective: (Physics only) (HT only) Apply WS 1.4 when interpreting diagrams and graphs of generator-effect devices.. Which answer is most accurate for Uses of the generator effect (HT only)?

- A.Uses of the generator effect (HT only): wind-turbine generator power-link shows (Physics only) (HT only) Apply WS 1.4 when interpreting diagrams and graphs of generator-effect devices. 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).
