Magnetic fields: bicycle dynamo boundary shows Define a magnetic field as the region around a magnet where a force acts on another magnet or on a magnetic material. because magnetic effects depend on field direction, current or changing magnetic flux.

Magnetic fields: bicycle dynamo boundary shows Define a magnetic field as the region around a magnet where a force acts on another magnet or on a magnetic material. 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 bicycle dynamo boundary detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
