Answer 1

for finding the polarity of the two faces of a current carriying circular coil,the following rule applies:
"When an observer,facing the circular coil,finds the current to be flowing in the anticlockwise sense,that face of the coil behaves like the north pole of the equivalent magnet.On the other hand,if the current is seen tobflow in the clockwise sense, that face of the coil brhaves like South pole of the equivalnet magnet."
