Question

A wire, bent into a circle, carries current in an anticlockwise direction. What polarity does this face of the coil exhibit?

• A. North
• B. East
• C. West
• D. South

Answer 1

The correct option is A North

Since the face appears to carry current in anticlockwise directions, the magnetic field seems to come out of that face.Since the curled fingers of your right hand show direction of current and thumb points to the north pole.
The magnetic field enters the south pole of the bar magnet and comes out of the north pole of the bar magnet. Hence the face has polarity as that of north pole.
