Which explanation best links the observation to the physics? Context: National Grid substation 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): National Grid substation 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 says field lines travel from south to north outside the magnet. (efficiency error).
- C.It makes AC and DC equivalent. (energy-transfer error).
- D.It ignores relative motion or changing magnetic flux. (field-shape error).
