Which explanation best links the observation to the physics? Context: laboratory bar magnet AC-output. Learning objective: (Physics only) (HT only) Describe how a potential difference is induced when there is a change in the magnetic field around a conductor.. Which answer is most accurate for Induced potential (HT only)?

- A.Induced potential (HT only): laboratory bar magnet AC-output shows (Physics only) (HT only) Describe how a potential difference is induced when there is a change in the magnetic field around a conductor. 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. (power-link error).
- C.It makes AC and DC equivalent. (exam-command error).
- D.It ignores relative motion or changing magnetic flux. (direction error).
