Which conclusion keeps the magnetism concept boundary clear? Context: school bell electromagnet AC-output. Learning objective: (Physics only) (HT only) Explain how headphones use the motor effect to produce sound.. Which answer is most accurate for Loudspeakers (physics only) (HT only)?

Loudspeakers (physics only) (HT only): school bell electromagnet AC-output shows (Physics only) (HT only) Explain how headphones use the motor effect to produce sound. because magnetic effects depend on field direction, current or changing magnetic flux.

Loudspeakers (physics only) (HT only): school bell electromagnet AC-output shows (Physics only) (HT only) Explain how headphones use the motor effect to produce sound. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Loudspeakers (physics only) (HT only), uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The school bell electromagnet AC-output detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
