For those of you who have had an interest in levitating graphite, you may f= ind interesting a prototype instrument that I recently built. I first witn= essed the intriguing possibilities of diamagnetic levitation through a demo= nstration by Chris Chapman about half a decade ago, when I visited with him= in England. Only recently did I come to know about pyrolytic graphite (PG= ) plates, as opposed to the earlier experiments with rods. Because the pla= tes are amenable to use with my fully differential capacitive sensors, I de= cided to try my (typically frustrating) hand at building such a tiltmeter/s= eismometer-that I have called in the following online paper an 'earth motio= n' detector. http://physics.mercer.edu/hpage/diamagnetic/diamag.html The outstanding performance of this prototype really surprised me.
