   If I were to shoot a charged particle , electron , at your two magnets   
   that are repelling I would know is it is south south or north north that   
   are facing each other. Your cell phone has Hall effect tansisters inside   
   to help with GPS. If you download an app such as compass it will also   
   know if it is south south or north north. It works on the same principle   
   as a moving charge.   
      
   Interesting side point. If you glue 6 magnet together with all north poles   
   faceing in like a mono pole it will stop being a magnet. The south poles   
   on the outside will not stick to a fridge. It measures zero magnetic   
   field with a cell phone. I find it odd that it  loses all magnetism if   
   there is only one north or one south pole.   
      
   [[Mod. note --   
   1. Hall-effect magnetic-field sensors may make use of transistors,   
      but I don't think there's any such a thing as a "Hall-effect   
      transistor".   
   2. I am skeptical of your glue-6-magnets-together claim.  References?   
      More detailed description of experiments you've performed yourself?
