Select the statement that would earn credit in an AQA GCSE Physics answer. Context: power-station transformer field-shape. Learning objective: (HT only) Use Fleming's left-hand rule to represent the relative orientation of force, current and magnetic field.. Which answer is most accurate for Fleming's left-hand rule (HT only)?

- A.Fleming's left-hand rule (HT only): power-station transformer field-shape shows (HT only) Use Fleming's left-hand rule to represent the relative orientation of force, current and magnetic field. because magnetic effects depend on field direction, current or changing magnetic flux.
- B.It swaps motor and generator reasoning. (safety error).
- C.It describes gravitational force instead of magnetic force. (efficiency error).
- D.It claims induced current is supplied by a cell. (energy-transfer error).
