Your coil doesn't look too promising, does it? ;-)
Actually, I don't think the equation quoted has a whole lot of relevance
to the discussion. Per my best recollection, this is a quantum physics
relation between the energy in a single photon and that photon's
frequency. So if your coil's output consists only of radiated energy
(that's photons) and only radiates them so rarely that you can distinguish
individual ones, then we may wish to consider it of use. Otherwise, we may
need to exercise some real creativity to apply it here.
Actually plugging in a few numbers as you did can provide a useful sanity
check. Take care...
