Magnetic fields: laboratory bar magnet application shows Describe the direction of a magnetic field as the direction of the force on a north pole placed at that point. because magnetic effects depend on field direction, current or changing magnetic flux.

Magnetic fields: laboratory bar magnet application shows Describe the direction of a magnetic field as the direction of the force on a north pole placed at that point. 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 laboratory bar magnet application detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
