[TCML] Tesla's spinning egg of Columbus

[finn hammer]

Gary,

So it did to me last time the subject was up, but I was informed that 
when the fields from adjacent windings oppose each other, the resultant 
field leaves the core quite freely. As in Television Tube deflector coils.

Ed Phillips answered it, so I don`t question the  answer.
