Am I right in understanding that one frequency is the test frequency 
and the other is the natural resonant frequency of the coil? If so, 
isn't the test frequency arbitrarily chosen? If that is true, why 
should there be a relationship between them? Sorry for *my* 
confusion. I obviously haven't been following this closely enough.
