Electromagnetism: phone speaker coil energy-transfer shows (Physics only) Interpret diagrams of electromagnetic devices in order to explain how they work. because magnetic effects depend on field direction, current or changing magnetic flux.

Electromagnetism: phone speaker coil energy-transfer shows (Physics only) Interpret diagrams of electromagnetic devices in order to explain how they work. 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 phone speaker coil energy-transfer detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
