Poles of a magnet: overhead cable transmission direction shows State that two like magnetic poles repel each other. because magnetic effects depend on field direction, current or changing magnetic flux.

Poles of a magnet: overhead cable transmission direction shows State that two like magnetic poles repel each other. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Poles of a magnet, uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The overhead cable transmission direction detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
