Re: [TCML] Toroid Shielding

["Phil Tuck" <phil@xxxxxxxxxxx>]

Yes, I know what it is called. How though does the effect manifest itself on a tesla coil?  

Does the overall width of the toroid create a vertically  descending field that pushes or deflects  the streamers away? This field diminishing in effect the further down the coil it travels. So in effect, if it could be seen, it would appear as an inverted cone with the base of the cone being the same as the overall diameter of the toroid? 

A bit like this:  http://hvtesla.com/temp_images/img004.jpg
