define end rule
Dear student,
The magnetic polarity of the current carrying solenoid is given by end rule
(a) When looked from one end if the current through the solenoid is along clockwise direction the nearer end corresponds to south pole and other end is north pole.
(b) When looked from one end if the current through the solenoid is along ant-clockwise direction the nearer end corresponds to north pole and other end is south pole.
