A solenoid is the long coil of a circular loop of any conductor. the magnetic field lines inside the solenoid are parallel to each other just like in a permanent magnet.

the magnetic field lines outside the solenoid are also similar to that of the permanent magnet. and hence we can assume the end from where the field lines emerge as the North Pole and the end where the field lines merge as the South Pole.

When we bring the North pole of a bar magnet towards one side of the solenoid if it repels the side of the solenoid is North and if it attracts then the side of the solenoid is South. The polarity of another side will be opposite.
