RE: New coil takes shape

It sounds counter-intuitive until you actually look at one.  See
http://users.rcn.com/laushaus/tesla/primary_files/image003.jpg
This shows the point where the top and bottom coils are joined in the
center.  If both coils had been constructed identically, the current
flow would make an abrupt reversal between the coils, and their
inductance would cancel each other rather than reinforce each other.
