Peter
thanks for posting that information from Mark Dansie ,
Below is screenshot of the spec sheet/information (CMD5005) from one vendor I contacted at Verpies suggestion in US

So CMD5005 are the specs we are aiming for as we find sources in Marks links !
Here the complete spec sheet on one alternative ferrite .

Page 04 has the overview of their ferrites

Page 15 has the specifics on this FN200 ferrite ( mentioned in previous post.)

PS
these materials are for the spider core experiments which Itsu has started to build and we need some high permeability ferrite components to complete .
A dedicated thread for this will be hosted in itsu's bench.

Ok passing a message on from Mark via Chet

You can see model FN200 has a permeability of 2000 and its spells out the other characteristics see attached image.

this is a webpage you can use to send enquiries to over 300 manufacturers and the drawing you sent would be good to show them

They all speak great english
My people in China do not specialize in Magnetic materials but are willing to help one to identify the supplier that meets your needs
There are thousands of suppliers not just 300

To measure a propagation delay, we need a signal which, when it crosses a threshold in either direction, triggers the start and stop of the stopwatch.
In the quasi-stationary regime – that is, in any region where the wavelengths associated with the signals are considerably longer than the dimensions of the system – the variation in the signal is far too slow; at two different points, the signal is virtually the same, making it impossible to take a measurement by detecting a threshold.
As for doing so without a threshold, simply by observing a phase delay, the result is incorrect because, once the regime is established, it is a steady state resulting from an incident signal superimposed on the signals it induces or that are reflected, so that one can no longer speak of the departure and arrival of a single signal.
Whilst it is easy to measure the delay of a signal of several MHz in a 10-metre cable, as each half-cycle produces a pulse, it is virtually impossible to do so with a 1 kHz signal, whose slope will be virtually constant at every point unless the cable is several kilometres to tens of kilometres long.
The commonly held belief that, because the signal is square-wave even at 1 kHz, there is a sharp edge allowing a delay to be distinguished, is equally false. Even if we did not have standing waves – which requires the utmost experimental care, particularly for a spread-spectrum signal such as a square wave – the measurement taken will be of the propagation time of the high-frequency component – for example, the 2000–2 MHz harmonic – and we will know nothing about the speed of the 1 kHz component, which is certainly different. Not only do permeability and permittivity influence the propagation speed and are generally frequency-dependent, but the path taken will also differ; for example, a high-frequency component may pass through a coil via a capacitive effect, without following the wire.

All that goes without saying.

Even less measurable would be the action/reaction time associated with a magnet falling into a tube, given that the magnetic field varies extremely slowly over time.

(The magnetic field created by the variation in the magnet's flux within the tube is felt almost instantaneously by the magnet itself, which continues its path whilst immersed in the field resulting from the superposition of the two, his own and that of the reaction.)

In your your words above that would be the case if the reaction frequencies of polarities were the same, but not if the reaction polarity is changing at a specific rate with the changing incident rate of polarity change.
https://en.wikipedia.org/wiki/Poynting_vector

In any case, a delay does not alter Lenz's law.

Who said it does? Really it is all to do with the action and reaction of magnetic fields, and rates of change with one another, which are special.

If there is propagation, it is because energy is carried along step by step, for example in a ferromagnetic circuit, with action and reaction occurring with the medium at every moment and at every point.

There is no ferromagnetic material in this device - that would be very detrimental as there is sufficient heat as it is due to induction (the inductive furnace effect), and has to be removed.

Soon we will be renewing our hosting package, we are currently EUKhost, i would like to see if anyone has ideas where we could move to, we have just under 20GB data attachments.
We currently pay around £150 a year for hosting and Certificate.

It would also be great to upgrade the forum software at the same time.

So looking for options, also the UK and EU are restricting free speech to also needs to be taken into account, freedom of speech within reason etc.

Everything is as usual with Tesla.
Shocks are created in the inductor, which create high-frequency oscillations in the current circuit. These oscillations should not decay, since this is our high-frequency current. And then, as I showed, the current is modulated to industrial frequency and amplitude. The chokes will protect the transformer from impulse interference from the spark generator

Kapanadze also talked about the Smith board - you can't get more than 50 kilowatts from it... Well, why not use the Smith principle to create high-frequency current?

Here some suggestions for sourcing such materials .

The printer I used for the frame sections had an issue that I have now resolved. I reprinted those parts and also made the dual ring gear, or hybrid ring gear, a little stronger so it is less prone to deforming under load. I also found two bad pivot bearings and replaced them.

As tested:

28 bearings
17 gears

Blue motor alone: 0.07 A

1:1 direct head-to-head, 1 Blue driving 3 Yellow:
0.48–0.50 A

2:1 system, no load motors:
0.16–0.23 A

1:1 system, no load motors:
0.18–0.24 A

2:1 head-to-head through the system, 1 Blue driving 3 Yellow:
0.45–0.54 A

All tests were run at the same 6 V power-supply setting and allowed to run until reasonably stable.

These are the measured numbers from this build. They are not being presented as evidence of gain; they are simply the results from the current configuration.
