Magnetic fields: moving-wire motor effect boundary shows State that the force between a magnet and a magnetic material is always attraction. because magnetic effects depend on field direction, current or changing magnetic flux.

Magnetic fields: moving-wire motor effect boundary shows State that the force between a magnet and a magnetic material is always attraction. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Magnetic fields, uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The moving-wire motor effect boundary detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
