You're right: I forgot about the capacitance. I think that it would be 
impossible to make a coil in this way that had a high enough L/C ratio to 
get a reasonable magnifier alignment. The secondary needs much more 
inductance and less capacitance. I've been playing aroud with the Magsim 
program (still haven't found the quit button) to get a handle on the problem.

Some questions about your magnifier theory: If I'm designing a 1:2:3 
alignment, does that mean that I make the resonant frequencies of the three 
circuits (uncoupled) in the ratio 1:2:3? So I make a primary that rings at 
100kHz, a secondary at 200kHz, an extra coil at 300kHz, and just stick them 
together? Or does the ratio refer to the three normal modes of the coupled 
system?
