Which conclusion keeps the magnetism concept boundary clear? Context: iron-filings field pattern voltage-change. Learning objective: (HT only) State that a coil of wire carrying a current in a magnetic field tends to rotate.. Which answer is most accurate for Electric motors (HT only)?

Electric motors (HT only): iron-filings field pattern voltage-change shows (HT only) State that a coil of wire carrying a current in a magnetic field tends to rotate. because magnetic effects depend on field direction, current or changing magnetic flux.

Electric motors (HT only): iron-filings field pattern voltage-change shows (HT only) State that a coil of wire carrying a current in a magnetic field tends to rotate. 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 iron-filings field pattern voltage-change detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
