Magnet coil cores, demagnetization power and Lenz delay.

[MarkE]

@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?

Synchro1, I have explained the physics several times already:   Lorentz force from an electromagnet can be delayed by either or both:  eddy currents that oppose the field formed by a time varying current, and magnetization of a pole piece due to magnetic viscosity in the pole piece material.  Similarly, observable BEMF can be delayed by each of those effects alone or in combination. 

As you now acknowledge that "Delayed Lenz Effect" is a misnomer, kindly stop using that incorrect and misleading term.

@MarkE,

What you wrote above is completely incomprehensible. You may think you're making sense, but I can assure you, MarkE, that your communication skills are extremely poor. You need a basic course in English composition. There's a chance you may understand what you are trying to say, but there's a huge failure on your part to put your thoughts into understandable language.

@MarkE,

A rotor magnet passes a ferrite core and the magnetic field from the passng magnet transits from point A to point B through the core. What happens to the timee interval if we increase the magnetizem in the core? Why would anyone want to bypass all the conventional theories and jump to the Lorentz force to help solve this simple problem?

So you are saying that the lenz force that act's against the rotor magnet can indeed be delayed.
It is my understanding that that is what is being ment by! delayed lenz effect!-the apposing magnetic field acting against that of the magnetic field on the rotor is delayed until such time that it pushes the PM away from the coil in an asisting direction.

Lets look at a simple Mag Amp:


"To begin, I would like to first show a simple experiment that demonstrates how saturating a magnetic core can lower inductance and allow more AC current to flow through a lamp. The lamp glows brighter when the magnets are near the transformer. The magnetic field saturates the core, lowering the inductive reactance in series with the lamp".
