Which explanation best links the observation to the physics? Context: scrapyard lifting magnet comparison. Learning objective: Describe how the strength of the magnetic field around a wire depends on distance from the wire.. Which answer is most accurate for Electromagnetism?

Electromagnetism: scrapyard lifting magnet comparison 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: scrapyard lifting magnet comparison 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 scrapyard lifting magnet comparison detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
