Muller Dynamo for experimentalists

@TEKTRON,

             Exactly, that's why I went with snug fitting diametric tubes.

Magnetic domain-wall velocity enhancement induced by a transverse magnetic field

@Wings,
Unfortunately this paper applies to permaloy nanowires, one can not apply these findings to ordinary ferrite I am afraid.

I looked for the comment of Winsonali and found it as well.
The 10 ms he is referring to is just 10 ms part of a 20ms pulse.
If one pulses a coil that has a non-liniar core, the core starts with a high value inductance and as soon as the core reaches saturation the core value decreases significant. This causes a large increase in current through the coil.
The current delay is caused by the coil value, not by the magnetization speed of the core materials in my view.
One can do a simple experiment to proove that.
Just put a load on the secondary of such transformer with similar core material. The current will increase much faster than in the case of a none loaded secondary. 
This is caused by the counter flux. If the core material would be 'slow' then the counter flux would be delayed and one would not see this effect.

99 % of research is in nanotech and so the paper ...

IMO the effect at our scale is effective see Energia Celeste device with in mind the last paper posted or Naudin orbo test :

but now we are far away from this forum.

Wings, I hessitate to accept that the paper that shows the magnetic lag while increasing the flux is applicable to normal ferrite cores with the time scale that is shown in the paper you refer to. I can't find any comparable results published before the 'nano' period.
I am sure this has been investigated earlier.

It's a long time since I reviewed Naudin's findings on Orbo.
I did some experiments with magnetic biasing of ferrite cores last year, so this is a kind of a dejavu.

My experiences with magnetic biasing was quite educating.
In general I found that you can 'tilt' the B-H curve by a magnetic bias (clockwise tilt looking at the B-H curve).
I did this in a stationary situation.
Tilting a B-H curve means changing the maximum coil value and changing the + and - RM level.
Translating this to moving magnets, I see that the only difference between RomeroUK's setup and a normal pulsed DC motor is the pulsed magnetic bias to the stator coils.
I need to think this through to come to a good conclusion why this would lead to energy gain, but it certainly is a gap in my experience.

my experience is much less than yours, just a reading hobby with small experiments.
I read a document in the past by Cyril Smith that speculated about OU from a cycle by BH magnetization.

now no longer found in internet and I have only one copy on paper and I will find it.

thought: in this case the ferrite core domains are aligned in some direction, direction changes do not start from random arrangements that involving more flipping energy ....

in any case more in: phase i.e. more rapid, more powerful

Energia Celeste have the pulse delay coils installed within the magnet!!

Kunel also ?
