Select the statement that would earn credit in an AQA GCSE Physics answer. Context: power-station transformer energy-transfer. Learning objective: (Physics only) Interpret diagrams of electromagnetic devices in order to explain how they work.. Which answer is most accurate for Electromagnetism? Distinct revision anchor: fluxcue371a coilcue371b fieldcue371c polecue371d gridcue371e motorcue371f generatorcue371g transformercue371h compasscue371i currentcue371j voltagecue371k forcecue371l.

Electromagnetism: power-station transformer 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: power-station transformer 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 power-station transformer energy-transfer detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
