1)The end of the electromagnet where the direction of current is clockwise is the north pole.
2)The end of the electromagnet where the direction of current is anticlockwise is the south pole.
3)The end of the electromagnet where the direction of current is clockwise is the south pole.
4)Magnetic polarity does not depend upon the direction of the current through the coil.
