Which explanation best links the observation to the physics? Context: laboratory bar magnet coil-core. Learning objective: (Physics only) (HT only) State that an induced current generates a magnetic field that opposes the original change.. Which answer is most accurate for Induced potential (HT only)?

Induced potential (HT only): laboratory bar magnet coil-core shows (Physics only) (HT only) State that an induced current generates a magnetic field that opposes the original change. because magnetic effects depend on field direction, current or changing magnetic flux.

Induced potential (HT only): laboratory bar magnet coil-core shows (Physics only) (HT only) State that an induced current generates a magnetic field that opposes the original change. 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 coil-core detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
