Boyd Bushmans levitating coil.

I have tried this myself and it works great but i was just wondering EXACTLY how it works, i have googled but cant find any good info on it, if somebody with a physics background could give some insight into this phenomena it would be great.

Heres the link: http://www.americanantigravity.com/bushman.shtml

it looks as if the conductive surface below it causes the two objects to repel each other.

 

I couldn't find details about the circuit or how the device supposedly worked. could you post anouther link with that information please
