Re: [TCML] ELECTROMETERS
Wow over a year! That's intense.
I thought it was from electrons becoming trapped within the dielectric layer. And those closer to the outer parts of the layer would remain there until presented with a suitable ground (my hand). Sort of how lichenberg (spelling) figures work.
So thicker layers would store more and bite people more
Has anyone noticed a correlation to the thickness of the coating and how bad I bites?

I've experienced the same ever year when I run my coil outside during
Halloween. Currently, the coil I'm using has about a 1/4 inch of epoxy
coating the surface. Even after 1/2 hour or more after a Halloween run, the
static build-up on the surface of the coil can be startling, if you are not
prepared. This happens year after year, and is independent of what coil I
happen to run. I always find it a bit odd, given that the humidity around
Washington DC is usually fairly high. I would expect the charge to bleed
I always wanted to know if it was always the same polarity or if it was a
positive or negative charge. Possibly more important, why is there a
residual parasitic charge? I speculate that it is due to the fact that the
Earth is charged with respect to the ionosphere, though I suppose that it
could also be a residual parasitic charge resulting from coronal
rectification, whatever that is. I also wonder if other people experience
the same when they run coils indoors, or is this just something that happens
