An insulated copper wire is wound on a soft iron core. Current is passed through the coil such that at end A the current flows anti- clockwise and a magnetic compass needle placed at other end B of the coil. a) What polarity is created at B? b) How is the magnetic compass affected when current flows through the coil?
