Magnet coil cores, demagnetization power and Lenz delay.

[Pirate88179]

Who ever said "Lenz's Law" is being delayed?

But the topic is: Magnet coil cores, demagnetization power and LENZ DELAY.....right?

What is the difference of what Lenz's law stipulates and Lenz delay?  If you are not delaying what Lenz is referring to then what is being delayed then?

@Bill,

Here's the important fact: kEhYo gets DLE in his coil shorting video at a frequency of 7200. that's six magnets and a rotor speed of 1200 R.P.M. Gotoluc's CMF is 70k at 35k R.P.M. wth no backing magnets on his ferrite output coil core. That's nearly thirty times the rotor speed to benifit from the effect. The vast reduction in threshold speed is caused by the backing magnets. This only effects the viscosity in the gap between the rotor and the coil and has nothing to do with "Lenz", "Faraday", "Maxwell",  "Lorentz", or "Albert Einstien".

The "Delay" is caused merely by this viscosity barrier and the time it takes for the reflected coil field to reach the rotor magnet. There's only one cause for DLE, not multiple causes!

OK, thank you for your explanation.  I am not sure if it is correct or not as now you are over my head.  I do appreciate your answering my questions though.

Thanks,

Hi folks, Hi synchro, don't remember where i got this file from, could have been here, though it is worth reposting.
The document seems to describe, what you are saying.
I will be trying to emulate this behavior in my magnet eddy current heater as well.
It uses a belt and pulley setup, so i can crank up the rpm's and try different aluminum pieces and distances to try and get ahead of the coils reflection or in my case, the aluminums locally induced field.
peace love light

Bill, what Synchro1 describes is in no way a delay in effects described by Lenz' Law. Synchro1 describes observations where induced EMF from Faraday induction or torque from Lorentz forces is out of phase with an inducing magnetic field.  The reasons for those observations and their net meaning have been described.  Synchro1 rejects those descriptions but has failed to refute them.
