Question
- A. Magnetic fields: school bell electromagnet measurement shows State that magnetic field lines go from the north-seeking pole to the south-seeking pole of a magnet. because magnetic effects depend on field direction, current or changing magnetic flux.
- B. It swaps motor and generator reasoning. (measurement error).
- C. It describes gravitational force instead of magnetic force. (diagnosis error).
- D. It claims induced current is supplied by a cell. (prediction error).
Answer
Magnetic fields: school bell electromagnet measurement shows State that magnetic field lines go from the north-seeking pole to the south-seeking pole of a magnet. because magnetic effects depend on field direction, current or changing magnetic flux.
Explanation
Magnetic fields: school bell electromagnet measurement shows State that magnetic field lines go from the north-seeking pole to the south-seeking pole of a magnet. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Magnetic fields, uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The school bell electromagnet measurement detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.

Common mistake
generator-effect induction: avoid permanent and induced magnets
Treating permanent and induced magnets as interchangeable when answering about generator-effect induction.
Instead, identify the exact Unit 4.7 idea in Magnetic fields, then explain how it links to a moving-coil microphone investigation and the objective to state that magnetic field lines go from the north-seeking pole to the south-seeking pole of a magnet.
