I've read that when an electret pole is move linearly across a pole of a 
permanent magnet that a perpendicular force is exerted on the electret. 
  This force is not attraction or repulsion, but exerted 90 degrees from 
the path of movement of the electret.

If so, could this this just be a different face of our old friend the 
Lorentz force which is applied to steady state electric and magnetic 
fields?  But, isn't the Lorentz force applied to a conductor with a 
current within a magnetic field?  So where's the current with the 
permanent and electret?  Maybe the Lorentz force doesn't need a current 
conductor.  Maybe the Lorentz force is a "field" phenomenon.  Perhaps an 
unrecognized quantum effect.

What geometry of electrets and Tesla coils would allow shaping of the TC 
field?  Could a directed TC field be produced.  Perhaps a spiraling TC 
directed field?

Electrets are not hard to make, but with their commercial availability 
today (cell phones) does anyone know of a readily available source?  I 
would like to observe this phenomenon before speculating much further.
