Primary Coil strike rings
I've been looking at a few of the images from nic.funet.fi, in
particularly the wingate files, and was almost totally blown away!
Does anyone know the specs/locations of these coils?
All I can tell is that Wingate1.jpg is a magnifying setup, and
Wingate2.jpg is a dual-coil system - bloody awesome!
Anyway, I've been noticing a few people chatting, aswell as seeing these
in images, but Primary Coil strike rings - what technical info is there
to know about them, other than that there higher than the primary (so
there is no breakdown between), it's not a complete ring, and it's
I'm mainly interested in the mathematical side of designs for these,
aswell as coils in general.
