Can it be this simple? Magnetic Viscosity (lag) the key?

Few days back I’ve posted some comments on another thread re: how to measure magnetic viscosity/lag, or in few more words, the time it takes for a magnetic front wave to get transmitted through a magnetically conductive material.

Researching the net for Magnetic Viscosity this came up among others and the following graph may be of  interest:

It appears to indicate a measured lag of around 130 microsecs?

A setup for getting  passed the proverbial  sticky point using e.g. 0.5 inch (pole face dimension) set of mags, would be as follows:
you bring them together very fast, inside the 130 microsecs window and then the full repulsion kicks in and forces them apart. By the time the repulsion kicks in, the mags are on top of each other. About 320 fps should do it. If the setup employs neo mags on a disk 6 in dia, a rotational speed of 13krpm may do the trick? Interaction would be between mag on the disk perimeter vs a stationary etc. Both in repulsion.  Or antigear wise (counter rotating disks/mags for 1/2 the speed per each. With better viscosities (longer times) a slower speed would be needed?
The idea is to have a high enough -relative- speed between the two mags so on approach the integral of the repelling force over the distance traveled to the center (sticky) point, is less that that of the departing one.
At these speeds, high efficiency low friction bearing would help

Next for solid state, a driving coil that gets pulsed with a short enough duration, that by the time the magnetic front reaches the collection coil on the other side of the rod, (or transformer) the input to the pulse is off on the driving coil. However, the collection coil will see a rise and a fall of flux resulting in a voltage and a current if there is load put on it, but since the driving coil is off the power source by that time, there is no time for any BEMF to load/counteract the driving coil.!
This may best work out with a DC pulse, and ofc we’ll be getting a DC out. ( I wonder if the TPU works like this)
As an example:
Primary Pulse dc ON for 150 microseconds, pulse OFF for  10 or even 100 times that ( would even give a 60Hz based period. Etc.

Thanks

Ps: is this stuff patentable? It has been in public domain for quite some time. Can these principles and  designs be licensed?

Hi mikestocks2006,

I like to thank you very much for bringing this up. It certainly is a missing link to the subject of Lenz-Delay and Thanes
coil-setup. If this graph is real than we have a new approach and can act accordingly

I was responding to skywatcher123 in the Peripiteia-Thread and reasoned the possibility of a magnetic wave ( the longitudinal spread of permeability ) along the core-length which is reflected at the far end of the and thus reversing the polarity of the magnetic elements. ( Analogous to the reflection of an electric impuls at the far end of
an open coax-line )

Glad to see others see this. The lag can be so pronounced as to cause a reversal of rotation (lagging so much it appears to lead).

Also be aware the same lag occurs in mechanical non-magnetic systems where acceleration is the only force. Talk to someone that balances rotating machinery. It is fairly difficult to balance anything that is variable speed because the lag from mass and acceleration varies with the speed.

Of course, the book thumpers will soon chime in. No matter, I still must balance this type of machinery and I'll use what works.

This is exactly what we are doing at Ottawa University with our coils' self induced capacitance - our Lenz induced magnetic field is delayed by 90 degrees and repells the "charging" magnet at the exact instant said magnet is beginning to move away from the coil.

The delayed magnetic field does four things simulataneously:

1) Repells already receeding rotor magnet with additional force,
2) Attracts next approaching opposite pole rotor magnet
3) The delayed magnetic flux is "collected" and fed into out High Current Coil Cores increasing our output power by more than x10 to date.
4) The High Current "in phase" flux is also collected and redirected away from the rotor magnet (thus reducing armature reaction) and fed into the High Voltage Coil Core increasing and enhancing the HV Coil acceleration effects as well.
