Magnet coil cores, demagnetization power and Lenz delay.

[NoBull]

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

The topic of this thread.
You can achieve a delay in the response of a ferromagnetic core to the time-varying flux but no delay in the response of a coil to the same.

The "Delay" is caused merely by this viscosity barrier ...

If you'd call it a "Core Delay" you'd be technically correct, but "Lenz's law Delay" or "Lenz Delay" or "Delayed Lenz Effect (DLE)" are misnomers.

@NoBull,

I'm in complete agreement with you!

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.

@MarkE,

The issue I presented here involves the drop in "Critical Mínimum Frequency" or CMF  for "Delayed Lenz Effect" or DLE from attaching magnets to the ferrite cores of shorted output coils. You pretend you explained this effect somewhere. Can you describe simply and in plain english what the hell you're talking about?

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

Very interestiing! Good luck on your experiment.

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,

Bill

@Bill,

JLN demonstrated how DLE is caused by a phase lag in the core material. There are no additional causes. I dreamed up a few doozys myself. People fall in love with their own ideas. I continue to systematically apply JLN'S proof to all cases. This solves all the problems.
