Transformers (HT only): classroom plotting compass direction shows (Physics only) (HT only) Describe a basic transformer as a primary coil and a secondary coil wound on an iron core. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): classroom plotting compass direction shows (Physics only) (HT only) Describe a basic transformer as a primary coil and a secondary coil wound on an iron core. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Transformers (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The classroom plotting compass direction detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
