Partnered Output Coils - Free Energy

Well,

I think you agree that flux can and does travel around the toroid core.

With that in mind, what if for most toroids that we use day to day, the majority of the flux travels around and within the toroid core, rather than some around and some across, regardless of magnitude (assuming the core is not in saturation of course)? If that was the case, would it result in an induced voltage in the secondary? If not, why?

Are you saying that if the core were of the highest permeability, that the fluctuating field of the primary with ac applied, begins within the core underlying the primary coil, and forms an instantaneous linkage loop within the core without the field loop crossing over the cores open center?

Yes, that would be a fair description.

Does it makes sense to you? Do you see how an emf is induced in the secondary?

@Mags - According to standard Transformer Theory - You are correct.

A Core is selected for its Permeability specifically. Selected so it will operate well within its specified Flux Density's. There is a Right and a Wrong way to wind the Coils on the Core.

The Coils in the Diagram are not the correct way! The correct way, according to Transformer Theory is to Wind the Primary Coil the entire length of the Toroid as I believe Tinman correctly pointed out!!! If the Primary is not wound the entire length of the Toroid then a high amount of Flux Leakage is a very good possibility and as a result, extra Losses will occur.

When I say "Length of the Toroid" I mean around its entire Circumference.

It seems to me, because we are all having a good run, the distractors come back and stir up the nest, create some strife to upset the apple cart... Yes, you know who you are...

Not really. If the primary flux, well below saturation, is always encapsulated in the core, how does primary flux affect the secondary winding?? Where the 'Faraday' are you coming from?

Its almost to say that the stator core in a car alternator doesnt need open gaps on the inner diameter and the stator coils would be induced just as good as as with the gaps the way they are.
But they dont make them without gaps because the armature flux would not be able to flex into those gaps and 'cut' the secondary windings. Its a Faraday thing.

Im not considering that Poynt is a distractor.   But maybe we should see where this goes.  I would like to know if his further explanation makes sense or not. 

I have a book at home on switching supplies. It mentions the subject of how far to wind the toroid. Off the top of my memory , I believe it said not to wind all the way to the other end, but to make it shorter or even overlap the ends. Ill post the findings of that and explanations why when I get home. The book is next to the potty.
