OK, have it your way. But there are thousands of textbooks and tutorial websites that agree with what I show. Nobody else that I've ever seen, met or heard about does it your way.

Yes.
--- Quote ---This Induced E.M.F is a result of Faraday's Law of Electromagnetic Induction - Yes?
--- End quote ---
Yes
--- Quote ---So, this must therefore mean, that Current in the Output Coil will Symmetrically Oppose the Larmor Frequency Precession of the Atoms that are precessing - This is Lenz's Law, Negative of the Source.

Forgive me for correcting you but you have made errors in your statement. Firstly Lenz’s Law is not an absolute negative, it clearly states that the load current in the output coil creates flux that opposes the change in the applied flux. That is not an absolute negative, for sine waves it is a 90 degree phase shift. That 90 degree phase shift of the Lenz flux means that there are regions throughout a full cycle where the Lenz flux opposes the applied flux, and there are regions where the Lenz flux adds to the applied flux.
Secondly within a transformer Lenz’s Law is only part of the mechanism whereby energy is transferred from the source feeding the primary to the load applied to the secondary, or within a mechanically driven generator energy is transferred from the drive shaft to the load. Your statement “Lenz's Law, Negative of the Source” as an overriding law is incorrect. If you had said that the power delivered to the load will Symmetrically oppose (apply a load to) the precession motion of the Atoms that are precessing, then I would agree. But that precession motion is not of our making, it is perpetual and driven by the quantum forces of Nature. Thus we are no longer talking about a closed system, it is an open system.

A prototype will tell us who is right here wont it. When theory does not cut it, Bench work does!

I thought some people may be interested in my LH Rule for visualizing how the Curl operator applied to the magnetic vector potential A creates the resultant magnetic B field.
