- A.Poles of a magnet: National Grid substation direction shows Describe how two magnets exert forces on each other when brought close together. because magnetic effects depend on field direction, current or changing magnetic flux.
- B.It says field lines travel from south to north outside the magnet. (efficiency error).
- C.It makes AC and DC equivalent. (energy-transfer error).
- D.It ignores relative motion or changing magnetic flux. (field-shape error).
