Poles of a magnet: step-down charger transformer cause shows State that a permanent magnet produces its own magnetic field. because magnetic effects depend on field direction, current or changing magnetic flux.

Poles of a magnet: step-down charger transformer cause shows State that a permanent magnet produces its own magnetic field. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Poles of a magnet, uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The step-down charger transformer cause detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
