Hi Tao,
could you please post a few screenshots of your Bryce5 model ?
I am not at home, so I can?t look at Bryce models, maybe just a few JPEGs
would be great.

2. I guess the kicks could only come from the Barkhausen noise inside
the bailing ( iron) wire and it really needs this wire, in copper wire we don?t have
Barkhausen kicks.
Why it is around 5 to 6 Khz and not around 180 Khz is puzzling to me...
Maybe his LC resonance frequency is just around 5 to 6 Khz and
this is a beat frequency or a lower octave frequency of the Barkhausen
noise kicks at 180 khz ?
The open core TPU unit looks so easy to build, probably just about 4
coils and a few caps and the core, that is all...
He also said, it depends mainly on the setup of the coils
and phase relationship, so the feedback loop is very important
from the intial magnet induction and magnetisation of the iron
wire coils...

SM told something about mumber of waves / frequencies around the device?
I am not reading all the discussion,but i have some information related to this on my web-site

Here it was..

"He has also said the frequency is related to the circumference. To get a wavelength within the length of wire in one of the coils would mean frequencies in the gigahertz range ?  Or perhaps this is a way of saying standing waves are required ? Or perhaps this is a cryptic way of saying that resonant circuits must be used as the diameter of a coil affects the impedance of a coil which in turn affects the resonant frequency. Parallel resonance is an effective open circuit on the power source (infinite resistance). Serial resonance is an effective short on the power source (no resistance). I?ve been thinking whether these two effects can somehow be combined to good use. Parallel resonance for the input coils as it would use very little current to drive the circuit and serial resonance for the output coils in order to have very little resistance."

I have an Excel table, free to download from my web-site,select sheet MEC bifilar coil and you can get needed circumference dimensions and frequencies to have nested cylindrical field formation around the device.

If it would be wound around the center axis of this wood core
(like cylindrical onto the surface) , he would have to cut many more wires
and could not saw through it with a wood sawing unit !

They make metal cutting blades for those things.

Esa, nice info on your site. I'll be reading through it soon.

@tao where did you find that barkhausen effect stuff?
