Would anyone have any idea of the gauss measurement of a microwave magnetron 
magnet?
 
For the purpose of vortexing water I guess the measurement would need to be 
taken from the inside diameter of the hole in the magnet...if that's possible?  
I know those magnets vary in size depending on the microwave, but a rough idea 
would be good enough {by comparison to those tiny magnets in those vortexing 
gizmos advertised on the net}.
