Describe a magnetic compass as containing a small bar magnet.

Describe a magnetic compass as containing a small bar magnet. sits within Magnetic fields in AQA GCSE Physics Unit 4.7 Magnetism and electromagnetism. A strong explanation names the exact magnetic context, then links the observation to field direction, current, force, coil turns, induced potential difference or transformer power as appropriate. For this objective, revise the keywords compass and use them as evidence rather than as isolated definitions. Keep the boundary precise: permanent magnets are not induced magnets, motors use current to produce force or motion, generators use motion or changing magnetic fields to induce a potential difference, and transformers compare primary and secondary coils. The distinctive exam cue is lo47cue323 fieldmap323 coilpath323 transformerlink323, which separates this learning objective from neighbouring transformer, motor-effect and magnetic-field objectives while preserving the official wording.
