The variations on high frequency circuits past that
excepted as the best electrical displays of arcing
through air with a strong discharge and spectacular
arc length through space are essentially more accepted
as avante garde effects procured by the final "best
effects" made by a tesla coil. However the
autotransformer abilities of a secondary  to freely
vibrate at a faster rate as a higher harmonic of the
primaries vibration might  be reflected in teslas
magnifier system connections, where the final coil may
vibrate faster than the initiator sequence. This may
be explainable as 3rd harmonics in that high frequency
system.

It seems useful as a beginning to investigate how and
why auto transformers are used to begin with, if we
are to imagine how that high frequency analogy can
take place in an Oudin coil. I would speculate that
the Oudin coil secondary has a tighter bandwidth  and
would be tighter to tune than a secondary made from
spacing away from that made by the loose coupling and
spaced primary with a conventional tesla coil. The
whole secondary issue is the freedom to vibrate. In
the ordinary tesla coil secondary, that freedom to
vibrate is guaranteed by the spacing where a secondary
must be in loose magnetic coupling  with the primary
for it to respond as a bell that rings. With an Oudin
coil the secondary is made as a bell to ring but the
striking ringer somewhat sticks to the bell and damps
the vibration somewhat if all the dimensions are not
perfect. Perhaps it is the fact that those hf impulses
were more damped that made it a more experimental gig
for possible ?safe medical applications of the body.

For the subject of multiwound layered coils I have
made a 33 sec mpeg video of spark disharges between 9
miles of 23 gauge -at- 56 Henry wire on both sides of a
output arc, and also the kickbacks going back up the 9
miles of line on each side containing 20,000 ~ 6 inch
diameter winds to appear at its sourcings as a
kickback flash. This is linked at electrical kickback
