Magnetic fields: coil-and-galvanometer induction diagnosis shows Explain how the behaviour of a magnetic compass is evidence that the core of the Earth must be magnetic. because magnetic effects depend on field direction, current or changing magnetic flux.

Magnetic fields: coil-and-galvanometer induction diagnosis shows Explain how the behaviour of a magnetic compass is evidence that the core of the Earth must be magnetic. 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 coil-and-galvanometer induction diagnosis detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
