Thank you for this posting.In Dr moray's lab. He had 8 ft secondaries 12-16
in dia with 1 to 3 turn primaries of 3/8 thick 2 in copper straps to use in
his experiments.Note: morray was a Tesla contemperary who invented the
transistor (proven in court Morray Vs: Western electric) The resonant
frequency of those coils could be measured, but how do you calculate them.
They are small in relationship to wave length, but they resonate about 230K
hz in the setups. Tests and numbers don't match. But they work in his lab.
 Morray's grand son gave me acces to his grand fathers lab to study a
problem of people who could see results but could not make theory to match.
