I will try to answer your question from *my* perspective of what a
magnifier actually is. To the guys who are more familiar with the
technology, feel free to correct me if im wrong!
The way i see it, the 2-coil and 3-coil systems are just the same
thing, except where you are putting the leakage inductance of your
"resonator". In a 2 coil system, the secondary winding consists of
some L that is coupled and the rest is "leakage" and is left to
resonate with the self C and toroid C. In a magnifier, you are
chopping up the secondary into 2 parts. One part (the driver) is
highly coupled to the primary, so most of the L there is coupled. The
3rd coil is only coupled electrically (not magnetically) so all of its
inductance is leakage L and resonates. So all you are doing is moving
a section of your secondary winding off axis. So to actually answer
the question, no, there is no free energy, and there is nothing that i
can see that should make a magnifier more efficient than a 2 coil
system. I believe the over all coupling achieved turns out to be
roughly the same once you figure that the 3rd coil isnt coupled at
Dont take what ive written here as fact! Im only going by my limited
knowledge of things.
I would really like to hear what others have to say in response to
