- A.Magnetic fields: bicycle dynamo boundary shows Define a magnetic field as the region around a magnet where a force acts on another magnet or on a magnetic material. because magnetic effects depend on field direction, current or changing magnetic flux.
- B.It reverses the role of primary and secondary coils. (comparison error).
- C.It assumes transformers work on direct current without changing flux. (safety error).
- D.It states the turns ratio changes resistance rather than voltage. (efficiency error).
