induction!? mind=blown - that makes perfect sense... I always
   thought, "Oh it arcs, which..." and then my mind follows a
   straight line through, and branching off as if a lightning bolt
   through the system. But my mental model was flawed.

   Oh that's excellent to know. Induction effectively makes it a
   low-pass filter and phase changer... so.. if I'm understanding
   it right.. it seems to effectively bulldoze its way through the
   system... might also explain the low "buzz" noise [frequency is
   frequency tongue emoticon ] am I getting it ok? I welcome
   corrections here.
