Hi all, Gee....this is like a old mystery....finding a source of diamagnetic material....preferably the carbon/graphite manufacturer. The more blank walls, the internet presents, the more the challenge....ha. The only admitted manufacturer I found was: http://www.asbury.com/index-markets.html They do mention the total range of products, previously speculated on. I sent a inquiry via email, specifically mentioning the the diamagnetic susceptiblity of ~ 450 in dimensionless SI units, mentioned on: http://www.physics.ucla.edu/marty/diamag/ lev4sale.html. I really doubt I'll get a reply, being I'am a private individual and not a company..... One would think Union Carbide sells something, but their site doesn't even get into carbon/graphite, from what I searched. Thanks to all, for their present and ongoing interest/efforts in this maddening mystery search for a definite source. Levitating devices maynot be worth much for seismic purposes, but its sure interesting, with the mass (magnet) response to vertical and lateral stimuli, from what I've seen visually.
