Magnetic fields: temporary induced magnet measurement shows Describe how a compass needle points in the direction of the Earth's magnetic field. because magnetic effects depend on field direction, current or changing magnetic flux.

Magnetic fields: temporary induced magnet measurement shows Describe how a compass needle points in the direction of the Earth's magnetic field. 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 temporary induced magnet measurement detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
