Hi topper
A solenoid has a large number of close, insulated circular turns. The magnet at the centre of current carrying circular wire is along the axis, so when current is passed in a solenoid, the magnetc fields due to all circular turns are added and hence the field line becomes just as for a bar magnet...
Yess, we can determine the north and south poles of a current carrying solenoid with the help of a bar
magnet. For this we suspend the bar magnet freely and note its ends pointing along north and south directions and mark on these ends N and S
Now, we bring N-pole near one end of freely suspended current carrying solenoid; if there is repulsion, then that and of solenoid is N and S,but if there is attraction, then that end of solenoid is S-pole and the other N-pole.

Hello sir,
When current is passed through a solenoid coil,magnetic field produced due to each turn of the solenoid coil is in the same direction. As a result, the resultant magnetic field is very strong and uniform.The field lines inside the solenoid are in the form of parallel straight lines along the axis of the solenoid.Thus, the solenoid behaves like a bar magnet. One end of a solenoid behaves like a magnetic north pole while the other end behaves as the south pole.
We can determine the magnetic poles formed in a solenoid. The end of the current carrying solenoid which attracts the north pole but repels the south Pole of a bar magnet,is behaving as south magnetic pole.The other end,which attracts south Pole of a bar magnet but repels the north pole,is behaving as north magnetic pole. It is because like poles repel but unlike poles attract each other.
Hope this helps..........
Thanks.
