Canceling Lenz's Law - Methods

[BEP]

Lenz's Law is one consequence of the principle of conservation of energy. It is also a 'one size fits all' law.

It proves well with single loops of wire and solenoid coils. It does not prove well with flat spiral coils.

Unlike single loops and solenoid coils the flat spiral coil magnetic polarity is radial - not axial.

I don't purchase 'one size fits all' clothing either.

P.S.

I believe Thane's work is like driving your car with a hole in the gas tank for years and then plugging the hole to find your mileage increased. You can't defy Lenz's law but you can remove it from the equation.

So BEP removing Lenz from the equation is not defying the law?  That's also an intresting point you brought up about spiral coils. I don't believe I've seen any motor using spiral cores before. Hmm brings up food for the brain.

     A flyback transformer with a ballasted primary seems to run with gain as  it controls the core reluctance and retainance to very efficient levels.  Some force is  changing the core saturation parmeters back to status quo.  The forward current from the horizontal output transistor comes in at 15khz and produces heat from the voltage drop in the horizontal output transistor.  Then we drop some more voltage through a bank of leds and finally we drop the rest of the voltage with core saturation change.  Then the sawtooth wave goes into transition and the saturated core goes back to status quo real fast producing a kick voltage up to 27kv.  This voltage is not at the expense of the input current it is produced by core magnetism resetting to the ambient magnetic field parameters.  The faster the better.

OK, I wanted to chime in here because this subject if touching on some aspects of designs I am currently looking ot design.

What I want to know regarding Lenz's Law is the relationship of this Law to the BEMF or CEMF (NOT FLYBACK if you know the difference) also known as DRAG, not of an electric motor but on an electric  generator. This DRAG increases as the generator load is increased. Is this what you are talking about. If so, I have some ideas, but I wanted to now before anything else if Lenz's law is responsible for the drag on a motor. If someone can answer this question, I will then post how I see this. Otherwise, if this is not related, then I will simply say sorry for an off topic post.

In my book bemf/cemf and Lenz is the same thing.

To quote:
'The counter-electromotive force is the voltage, or electromotive force, that pushes against the current which induces it. CEMF is caused by a changing electromagnetic field. It is represented by Lenz's Law of electromagnetism.'
