Which response uses the correct technical wording for this situation? Context: split-ring motor kit force-link. Learning objective: (HT only) Link opposite forces on the sides of a current-carrying coil to the turning effect in an electric motor.. Which answer is most accurate for Electric motors (HT only)?

- A.Electric motors (HT only): split-ring motor kit force-link shows (HT only) Link opposite forces on the sides of a current-carrying coil to the turning effect in an electric motor. 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).
