Partnered Output Coils - Free Energy

[EMJunkie]

But face to face coils. If the powered coil has current going clockwise, producing an opposite current direction in the loaded or even shorted coil, then I think the coils might push away from each other.

I should explain further...

In a Transformer, the Primary Coil, when carrying Current, creates a Magnetic Field that has a Direction of Travel and also a Spin Direction on the Core. This is the Magnetic A Vector Potential: See Below Picture: Magnetic A Vector Potential.

This is Basically the Right Hand Rule!!!

If our Transformer has Two Secondary Coil's where one is Wound in the opposite direction on the Core, then it is Possible for the Secondary Coils to be Wired in Parallel without creating a Short Circuit in the Coils!!!

This also gives you access to something else not widely known, this configuration can and does increase the Voltage in these Coils, not only because we have twice the turns but for other reasons.

The Winding direction does not mean that Lenz's Law is reversed! It merely means that the already existing A Vector Potential that already has a Magnitude and a Directional Movement on the Core is not interfered with the same as it would normally be.

See: https://www.youtube.com/watch?v=iJsVSMQqCOM

It can add assistance to the already present Action On the core: The Magnetic A Vector Potential's Direction and Magnitude. All Lenz's Law effects are always - Negative to the Prime Action, but here we are aiming for: Action / Reaction / Counter-Reaction - Newton's Laws of Motion, where the Counter-Reaction is in the same Direction as the Action - assisting!

At the same time, Counter-Reaction opposes the Reaction!!!

I should mention, this does not explain entirely the excess energy, This action described is Flux Linking (emf = -dPhi/dt) and Flux Cutting is not explained (emf = Bvl)! I have attached again George I Cohn - Electromagnetic Induction for more information.

P.S: I am still learning also, like I said, I still don't have all the answers. I don't know all of it and in places I may not be correct, its just the best I can do with what I have.

The Hysteresis on the Core, as it moves through the BH Curve, creates something amazing, it can be heard as a clicking or a Hiss, called the Barkhausen Effect. See: Barkhausen effect demonstration - PIRA

As the Domains align, they create the sound, a Hiss, or clicking...

The Primary Coil does this on the Core as it moves through the Sinusoidal Current Waveform. This is the BH Curve, or Hysteresis...

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.

From the book Simplified Design Of Switching Power Supplies  by John D Lenk.

Where it describes the issue with winding 1 layer full length of a toroid core is on pg 52 under the subject of self resonant freq of inductors and transformers.

So the winding issue is increased capacitance if winding the whole core where the first and last winding are adjacent.

Supposedly leaving some gap or overlapping some reduces the windings capacitance to keep the self resonant freq as high as possible, where the recommended self resonant freq should be at least 5 to 10 times the operating freq of the supply. Nothing about winding lengths of beginning to end and such in the emi section of the book. Emi issues need to be either shielded or directed away from sensitive circuitry. As in if you use a pot core, mount it 90deg from sensitive circuitry.


Personally I might think that overlapping some may increase the self capacitance compared to butting the ends together. 

So would there be any uses for an inductor to be operated at its self resonant freq?

Thanks for sharing Chris

Here is another demonstration done by JLN  https://www.youtube.com/watch?v=ZFZ4vxedHOY

Hey Mags,

Not disagreeing with what you say, but merely pointing out minor differences in the requirements of High and Low Frequency Transformers.

Of course the frequency of SMPS can be around 15 to 50 kHz, some even higher, at around 100KHz...

For a Mains Transformer, 50Hz or for the US Grid Frequency, 60Hz this is of course not so much of a problem.

Most Mains Toroidal Transformers are wound full Circumference, see picture below:
