- A.Magnetic fields: moving-wire motor effect measurement shows Describe how a compass needle points in the direction of the Earth's magnetic field. 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).
