   To Mod note. I understand your skepticism. The leaps that have been made   
   in electrical engineering are mind blowing. I have lucked out in life to   
   be a part of this. A Hall effect transistor is actually about 300   
   transistors etched on a silicon wafer to construct a few op-amp. For   
   op-amp google early analog computers. These op-amps then amplify to   
   detect the smallest difference in voltage between two sides of a   
   conductor. This is where the detection of a magnetic field comes from as   
   a charge will shift right or left depending on a magnetic field.   
      
   As to a glue-6-magnets. It is sitting on my lab bench. You will have to   
   trust my integrity as a follow scientist that it measure no magnetic   
   field. When it comes to making measurements my living depends on not   
   making such mistakes. If I open this magnetic mono cube just a tiny bit   
   it will measure a magnetic field but not when closed into a perfect   
   cube. Vacuum rendering software model will come to the same answer if   
   that helps.
