Meredith- Belatedly checked out your website which graphicly (graphitely?) brought home to me that I, in my techno-myopia, have blithely missed this whole business of diagmagnetic phenomena which has blossomed in front of me on the PSN-L: why be here and now when I can be in Turkey 5 weeks ago? I'll grab John in the hall and get him to force-feed me on magnetic developments; the human brain is still the best random-access device around. -Edward PS. I didn't know you guys were so religous on Sundays. meredithlamb@.............. wrote: > Hi All, > > Lee Ann and I were invited over to John and Jan Lahr's > to explore stable/static diagmagnetic levitation today. > John has built afew devices, and we used acouple to > test out a variety of neodymium magnets of various > sizes and shapes; and also a variety of graphite/carbon > DC motor commutator brushes, for their effects. > > While we primarily tried a number of brushes, we were > also easily able to levitate about 5 different neodymium > magnets of different shapes and sizes relatively easily. > My preconception of difficulty in adjustments went out > the window.
