Select the statement that would earn credit in an AQA GCSE Physics answer. Context: overhead cable transmission comparison. Learning objective: Describe the magnetic field around a solenoid as having a similar shape to that of a bar magnet.. Which answer is most accurate for Electromagnetism?

Electromagnetism: overhead cable transmission comparison shows Describe the magnetic field around a solenoid as having a similar shape to that of a bar magnet. because magnetic effects depend on field direction, current or changing magnetic flux.

Electromagnetism: overhead cable transmission comparison shows Describe the magnetic field around a solenoid as having a similar shape to that of a bar magnet. 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 comparison detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
