Russ:
I will get into the thought experiment tomorrow. You are in the right ballpark, it's about the current value and it's a simple paper-napkin type of estimate.
I am curious about how you measured the inductance of the coil you are working with on the bench right now. I am wondering if it might be out of range for a hand-held inductance meter.
Also curious about the resistance measurement for the big coil. I am going to guess with a multimeter you have to keep the probes connected for perhaps 10 seconds to get a proper measurement.
