Electromagnetism: primary-secondary coil comparison efficiency shows Apply WS 2.2 when drawing magnetic field patterns for a current-carrying wire and solenoid. because magnetic effects depend on field direction, current or changing magnetic flux.

Electromagnetism: primary-secondary coil comparison efficiency shows Apply WS 2.2 when drawing magnetic field patterns for a current-carrying wire and solenoid. 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 efficiency detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
