Each depends on how it is built. Most circular magnets have the N on one flat and the other S, although they can be magnetised in segments. Same patterns possible with spheres.
Use a compass to map the patterns.

Has this anything to do with Burmuda Triangle? I recollect of having watched one of the documentaries on Burmuda Triangle. A spherical magnet creates such a strong magnetic field that anything coming in its magnetic field is likely to dissappear! As of polarity, there must certainly be some N & S pole for magnetism to take place. We know how to detemine the polarity, don't we?

Pass the current through the magnet.If the current is flowing in anticlockwise direction then the upper face acts as south pole and lower face as north pole.If cuurent is flowing in clockwise direction then upper face acts as north and lower as south
