Select the statement that would earn credit in an AQA GCSE Physics answer. Context: overhead cable transmission prediction. Learning objective: Describe how the strength of the magnetic field around a wire depends on current through the wire.. Which answer is most accurate for Electromagnetism?

Electromagnetism: overhead cable transmission prediction shows Describe how the strength of the magnetic field around a wire depends on current through the wire. because magnetic effects depend on field direction, current or changing magnetic flux.

Electromagnetism: overhead cable transmission prediction shows Describe how the strength of the magnetic field around a wire depends on current through 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 overhead cable transmission prediction detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
