Select the statement that would earn credit in an AQA GCSE Physics answer. Context: power-station transformer boundary. Learning objective: Define a magnetic field as the region around a magnet where a force acts on another magnet or on a magnetic material.. Which answer is most accurate for Magnetic fields?

Magnetic fields: power-station transformer 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: power-station transformer 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 power-station transformer boundary detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
