Which conclusion keeps the magnetism concept boundary clear? Context: iron-filings field pattern direction. Learning objective: (Physics only) (HT only) State that iron is used in the core because it is easily magnetised.. Which answer is most accurate for Transformers (HT only)?

Transformers (HT only): iron-filings field pattern direction shows (Physics only) (HT only) State that iron is used in the core because it is easily magnetised. because magnetic effects depend on field direction, current or changing magnetic flux.

Transformers (HT only): iron-filings field pattern direction shows (Physics only) (HT only) State that iron is used in the core because it is easily magnetised. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Transformers (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 direction detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
