pls give me suitable region with example
How come you deduce that AC doesnt produce a magnetic field? If there is a motion of electric charges, there is always a magnetic field. Your ceiling fan is a good example of an ac motor.
When electrons move in a conductor there is always lines of magnetic flux radiating out from the conductor. AC magnets change their polarity at the same freq. as the applied voltage/current. AC motors work by creating a rotating magnetic field in the stator (stationary part) that the rotor (moving part) tries to keep up with. The rotor magnets are usually created by the induction of current into the rotor windings, often aluminum cast into a laminated iron rotor.
