On passing current through a solenoid. Which of its end behave as a north pole or south pole explain ?

Explanation

When current flows from loop (coil) it behave as magnet. Its one face behave as N pole while opposite face will behave as S pole.
Which end of coil behave as N pole and which end behave as a S pole can be found by following method.
(1) When closed current loop is viewed normally and if the current seems to flow in clockwise direction then that side of the loop behaves as a south pole and the other side of the loop behaves as a north pole It is shown in figure.

(2) Similarly, if the current seems to flow in anticlockwise direction then the side of the loop towards eye behaves as a north pole and the other side as a south pole.
