Re: More maggie Q & A

I have always used at least 5X the inductance of the driver for the free
resonator coil, that has work for me, but may be more a "rule of thumb".
Antonio Carlos M. de Queiroz has posted some very interesting material
regarding this subject, and has a web site up regarding the "Ideal magnifier".
