solution:
When electric current flows through a solenoid, magnetic field is set up around the solenoid. One end of the solenoid behaves as north pole and the other end of the solenoid behaves as south pole. To determine the north and south poles of a current-carrying solenoid, bring the north pole of a bar magnet towards one end of the solenoid.
If the solenoid attracts towards the magnet, then that face of the solenoid is south pole. If the solenoid moves away from the bar magnet, then that face of the solenoid is the north pole.
