I just happened to respond to someone earlier today about extra coils.  Here
is my version...

The extra coil in the magnifier is a special case.  Just as a primary
inductance must be smaller than the secondary inductance, the resonant
transformer frequency must be smaller than extra coil frequency.  If they
are the same frequency or the resonant transformer frequency is higher, it
won't be able to push the extra coil.  But the resonant transformer
frequency cannot be too high or the frequencies will loose coupling.  In
fact, there are only two ratios that will work for driving an extra coil,
4/3 and 11/6.  4/3 is probably slightly better of the two.  At four thirds
the resonant transformer is perfectly set to swing the extra coil to a
higher voltage.  Remember, four thirds is the same thing as one and one
third.

When you swing a child in a swing, the ideal time to "push" is when the
child is one third the way into the cycle.  The swing is at the beginning of
the cycle when the child is in the position of no motion.  The first quarter
of the cycle is the child moving backward.  Half way through the cycle the
child is back in the zero position.  Three quarters of the cycle through and
the child is all the way forward at peak height.  The last quarter is
returning to the zero position.  So one third of the way through, the child
has completely come backward and is already gaining some momentum forward
due to gravity.  This is the ideal time to input new energy into the system.
The only other good time to push the child is when the child is 5/6 the way
through the cycle.

For all intents and purposes, the extra coil is not a part of the resonant
transformer system.  The extra coil is system of its own frequency and its
own quarter wave length that is powered by a resonant transformer system of
lower energy.  There is no "free energy" in this system, but the extra coil
is such a well tuned resonant system that it can accumulate lots of energy
from several smaller well timed pushes.
