- A.Poles of a magnet: alternator output trace direction shows State that two unlike magnetic poles attract each other. because magnetic effects depend on field direction, current or changing magnetic flux.
- B.It reverses the role of primary and secondary coils. (direction error).
- C.It assumes transformers work on direct current without changing flux. (cause error).
- D.It states the turns ratio changes resistance rather than voltage. (evidence error).
