- A.Poles of a magnet: phone speaker coil cause shows Describe attraction and repulsion between magnetic poles as non-contact forces. 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. (prediction error).
- C.It confuses the magnetic field with an electric field. (comparison error).
- D.It describes energy transfer but misses the force or field interaction. (safety error).
