Electromagnetism: primary-secondary coil comparison comparison shows Describe the magnetic field around a solenoid as having a similar shape to that of a bar magnet. because magnetic effects depend on field direction, current or changing magnetic flux.

Electromagnetism: primary-secondary coil comparison comparison shows Describe the magnetic field around a solenoid as having a similar shape to that of a bar magnet. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Electromagnetism, uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The primary-secondary coil comparison comparison detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
