Which response uses the correct technical wording for this situation? Context: model railway motor diagnosis. Learning objective: Describe how to plot the magnetic field pattern of a magnet using a compass.. Which answer is most accurate for Magnetic fields? Distinct revision anchor: fluxcue248a coilcue248b fieldcue248c polecue248d gridcue248e motorcue248f generatorcue248g transformercue248h compasscue248i currentcue248j voltagecue248k forcecue248l.

Magnetic fields: model railway motor diagnosis shows Describe how to plot the magnetic field pattern of a magnet using a compass. because magnetic effects depend on field direction, current or changing magnetic flux.

Magnetic fields: model railway motor diagnosis shows Describe how to plot the magnetic field pattern of a magnet using a compass. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Magnetic fields, uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The model railway motor diagnosis detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
