Electromagnetism: iron-filings field pattern comparison shows State that the magnetic field inside a solenoid is strong and uniform. because magnetic effects depend on field direction, current or changing magnetic flux.

Electromagnetism: iron-filings field pattern comparison shows State that the magnetic field inside a solenoid is strong and uniform. 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 iron-filings field pattern comparison detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
