Thanks Marshall, that is a good tip.  But how can i tell which is north, and 
south, and positive and negative on unmarked magnet?  Are these magnets any 
good, from a web catalogue?
Can it be used for the vortex structure magnetized water process?
I wonder which is N or S or positive or  negative.
 
"Tiny rare earth samarium cobalt magnet features a small ceramic disc on one 
side and a red dot on the other side. These tiny .20" Dia x .078" thick magnets 
are extremely powerful for their size. Made for an aerospace company they are 
perfect in every detail. We just brought in a pallet containing over 70,000 
pieces. Made by Drexel Magnetics."
 
Thanks.
