How can I identify the poles of the magnets? 
There are several simple methods that can be used to identify the North and 
South poles of neodymium magnets.
1)  The easiest way is to use another magnet that is already marked.  The North 
pole of the marked magnet will be attracted to the South pole of the unmarked 
magnet.
2)  If you take an even number of magnets and pinch a string in the middle of 
the stack and dangle the magnets so they can freely rotate on the string, the 
North pole of the magnets will eventually settle pointing North.  This actually 
contradicts the "opposites attract" rule of magnetism, but the naming 
convention of the poles is a carry over from the old days when the poles were 
called the "North-seeking" and "South-seeking" poles.  These were shortened 
over time to the "North" and "South" poles that we know them as.
3)  If you have a compass handy, the end of the needle that normally points 
North will be attracted to the South pole of the neodymium magnet.
