Confirming the Delayed Lenz Effect

[Newton II]

The same coil that causes DUL (deceleration under load ) when the rpm of a given rotor is, lets say, 2000 rpm, will likely surprise you by showing AUL when the rpm is 3000, because at the higher rotor speed, (higher frequency), there will be a greater coil current phase shift when under load, than at 2000 rpm.

May be you are right.   I don't believe in any 'delayed lenz effect'.    Actually action and reaction happen at the same instant.  Force always happens in pairs.  Action cannot be performed without reaction and reacion cannot exist without action.   If reaction is delayed  beyond action  then Newton's third law itself becomes invalid which is highly impossible.  ' delayed lenz effect'  is the funniest name that you can give to this phenomenon.  If AUL happens because of delayed lenz's effect,  then it should happen at all speeds of the rotor but we know that it happens only after crossing certain minimum speed.

I feel that AUL happens because  of remenance or residual force which is also portrayed in another experiment posted in this forum in which two U shaped cores with a shorted coil stick together even after switching off the source current.

Actually action and reaction happen at the same instant...

And this is where you are wrong...
When it comes to induction the reaction is not instant. It is restricted by the speed of light!
That is why there is a possibility for that 'trick' (Delayed Lenz) to happen.
Tesla knew that and that is why his transformer is so interesting.
Imagine pulsing a one turn primary (d=2m) with a nano second HV pulse and turning of the power...
The secondary in the middle will receive that disturbance of the field (which 'travels' through the air at the speed of light @~0,3 m/ns) ~3ns later!
So any EMF induced in the secondary is decoupled from the primary power, and that 'reflected BackEMF WAVE' can be harvested back in the primary.

Is it not?

But that is not the principle used in Thane Hein's device.   Is it not?   I am talking about the motor - generator set which is shown by overunityguide at the beginning of this thread.     Can you meet the above said condition in that motor - generator set?

That was an example for the speed of the 'disturbace' in air.
In the case of using a ferromagnetic core as a transfer medium for 'momentum' the speed will be much lower than the speed of light
For a conductive core, where there is lots of eddy currents the 'wave' slows down the most, hence the delayed effect can be observed at lower frequencies with solid iron cores. Laminated silicon steel cores are 'a bit faster highway' and ferrites are like a race track

Take a look at this video from MrAnguswangus

He can obtain the effect at very low frequencies as the core (a bunch of solid iron rods in 'U' shape) he is using provides significant delay because of its length (long path to travel for the wave) and eddy currents, IMHO.

Now a clue from Ed Leedskalnin's notes to use, solid, aluminium bobbins for the generator coils with ferromagnetic cores might be understood this way. It provided a closed loop flywheel effect for eddy current, slowing down the wave... like a permanent magnet slowly falling down through a copper pipe

The dynamics of the two different systems give rise to two different phenomenon. In the case of the two U shaped cores experiment, predominant reason for the sticking is residual magnetism.

In the case of the moving rotor magnets and generator coils, phase delays in coil current cause a phase delay in the core/coil's self induced magnetic field. It is this self induced field created by the coil's current, when the coil has a load, that normally has a breaking effect on the driver.
