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..

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.

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. It is correct because it anchors the response to Induced potential (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The laboratory bar magnet AC-output detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
