Now you have me wondering how an external magnetic field would influence the process, especially when using conductive particles.
IIRC somewhere I read about moon dust floating above the surface under certain conditions. Could that be related to a similar process? Here I am not referring to magnetic effects.

I always seek out positive feedback mechanisms and this might be another. Something of this nature could make sense since the particles with the initial charge impacts other particles nearest to them greater than those at a distance. It would be interesting to determine what characteristics are common to the powders most active. Do they polarize easily? Is the dielectric constant the most important parameter? Of course conductive particles could not behave this way since the charges would leak off.

That's the flaw in my theory. When two different substances rub together, one will probably have a greater electron affinity than the other, which would explain bulk polarization of charge, however the same can't be said for a single substance. I guess that's why they are so puzzled. Now I am too. :) Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
