- A.Microphones (HT only): primary-secondary coil comparison exam-command shows (Physics only) (HT only) Distinguish microphone generator-effect operation from loudspeaker motor-effect operation. because magnetic effects depend on field direction, current or changing magnetic flux.
- B.It swaps motor and generator reasoning. (cause error).
- C.It describes gravitational force instead of magnetic force. (evidence error).
- D.It claims induced current is supplied by a cell. (boundary error).
