Question
- A. Electromagnetism: moving-wire motor effect efficiency shows Apply WS 2.2 when drawing magnetic field patterns for a current-carrying wire and solenoid. because magnetic effects depend on field direction, current or changing magnetic flux.
- B. It treats a permanent magnet as if it only works when current flows. (exam-command error).
- C. It confuses the magnetic field with an electric field. (direction error).
- D. It describes energy transfer but misses the force or field interaction. (cause error).
Answer
Electromagnetism: moving-wire motor effect efficiency shows Apply WS 2.2 when drawing magnetic field patterns for a current-carrying wire and solenoid. because magnetic effects depend on field direction, current or changing magnetic flux.
Explanation
Electromagnetism: moving-wire motor effect efficiency shows Apply WS 2.2 when drawing magnetic field patterns for a current-carrying wire and solenoid. 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 moving-wire motor effect efficiency detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.

Common mistake
motor-effect force direction: avoid motors and generators
Treating motors and generators as interchangeable when answering about motor-effect force direction.
Instead, identify the exact Unit 4.7 idea in Electromagnetism, then explain how it links to a steel core electromagnet demonstration and the objective to apply WS 2.2 when drawing magnetic field patterns for a current-carrying wire and solenoid.
