Which conclusion keeps the magnetism concept boundary clear? Context: classroom plotting compass force-link. Learning objective: (HT only) Explain how the force on a conductor in a magnetic field causes rotation of the coil in an electric motor.. Which answer is most accurate for Electric motors (HT only)?

Electric motors (HT only): classroom plotting compass force-link shows (HT only) Explain how the force on a conductor in a magnetic field causes rotation of the coil in an electric motor. because magnetic effects depend on field direction, current or changing magnetic flux.

Electric motors (HT only): classroom plotting compass force-link shows (HT only) Explain how the force on a conductor in a magnetic field causes rotation of the coil in an electric motor. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Electric motors (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The classroom plotting compass force-link detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
