Skip,
I assume, the second "undriven secondary" means no primary linkage to
this
second system. The stuff would spark, but power would be down due to
the
lack of flux linkage to the second system. If the first driven system
were
grounded and tuned properly, a nearby grounded coil of exactly the same
resonant freq would really break out nicely provided it too were
grounded.
We did a lot of this type of thing in what we called "free resonance"
work
back in 1991 as we developed the magnifier systems here. the coupling
between the systems was more by direct(ground) and capacitive coupling
as
the mag coupling was truly 0.0
