Electromagnetism: primary-secondary coil comparison prediction shows Describe how the strength of the magnetic field around a wire depends on distance from the wire. because magnetic effects depend on field direction, current or changing magnetic flux.

Electromagnetism: primary-secondary coil comparison prediction shows Describe how the strength of the magnetic field around a wire depends on distance from the wire. 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 primary-secondary coil comparison prediction detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
