- A.Electromagnetism: laboratory bar magnet efficiency shows Apply WS 2.2 when drawing magnetic field patterns for a current-carrying wire and solenoid. 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. (power-link error).
- C.It makes AC and DC equivalent. (exam-command error).
- D.It ignores relative motion or changing magnetic flux. (direction error).
