The  Yoke had  very  much uncommon   chemical components in that  yoke.
It is considered by me as  dangerous  although  we didn't have tools  of analysis of that structure at the test site.
The side effects :
Everyone from 6 experimenters including me but possibly excluding Antannas who was   documenting  the event was affected.
Aidas the young guy start to lose hair and experiencing   terrible headaches.
Gintas was the oldest of us. the same  but little lesser,  he didn't lose hair.

I didn't start to have health problems immediately.

As Aidas mentioned that he  had previously problems while we tested  halogen  lamp acting as a load, where I was instructing Aidas over the internet
video   conference what to do ...
The positive effect of that   made me to go to Lithuania to see it  by myself.
At the very first minutes  in Kaunas  Test room Aidas  wanted to stop testing  and I was  afraid that my trip
all expenses and discomfort will be wasted. So I placed my head nest to the yoke under test and said that  this is only Aidas imagination.
I recall I felt hot, yes hot  right after placing my head  next to  yoke under  the test (in about 7-10 minutes  after ..)

I had terrible  headaches and I was losing balance for a about 3 months prolonging to 5-6 months  after the Lithuania Experiment.
So  I was able to walk, but changing position of the head made me to lose balance or when bending or  trying to touch my feet with fingers I was falling down..
Well not so much  falling down but I was looking for something vertical  next to me  in case..
Changing position from vertical to horizontal was a challenge, this ended definitively with free fall  .

this one  compacting metal powder shows exactly the same process as is used in cintered ferrites
https://www.youtube.com/shorts/QZThsst0RIg

Ferrite is a polycrystal, sintered material with high electrical resistivity. The high resistance of ferrite makes eddy current losses extremely
low at high frequencies. Therefore, unlike other magnetic components, ferrite can be used at considerably high frequencies. Manganese-
zinc(Mn-Zn) ferrites can be used at frequencies up to several megahertz.
The basic ferrite materials are obtained in an extremely high purity. These materials are mixed, calcined, milled, granulated, formed by
pressing, and sintered at a temperature of 1000°C to 1400°C, then machined. The electrical and mechanical properties of a particular
ferrite material are obtained by the material formulation and the processing applied. Extraordinary exacting process controls are required
to assure the high uniformity of product for which TDK ferrites are well known. Through the above processes, ferrite materials can be
optimized for specific applications.

You are taking  fine  iron  powder, wet it with water, place that into huge ceramic  horizonally rotating cylinders  and let it rust for  24 hours
while rotating. Than you soak the water , let it dry . The rust is preventing  the powder  particles  from conducting.
Than you place that powder in the form giving it  desire  shape ,  you add some  bonding compound and  press it  with
hydraulic press 500kg pressure . Than you  have very fragile form  called green stage ferrite.
 Than you place it into  furnace heating it till it particles bonds into solid stage.

Much gratitude.

 Lithuania experiment yoke assembly step by step one more time
Wesley

Summary so far:
So we have two  caduceus coil assembly  in Lithuania experiment.
Both  do the same job.
- one is winded  the way that  it  not allow  to disassemble it or change alignment  of the components
 but you can still place inside of it ferrite as deep as you need it.
  picture :   https://overunity.com/19358/caduceus-coil-building-and-testing/dlattach/attach/189605/

_{Notice: when you press on these links  using Firefox browser -  that particular picture will be downloaded
instead of displayed so you need to open download to see them.}


- second one is made the way that it allows to  change the  pickup coil for another one with different 
  number of winds or  change caduceus  for  winded  with different geometry and number of cross points
  that was one part of experiment.

_{Notice: when you press on these links  using Firefox browser -  that particular picture will be downloaded
instead of displayed so you need to open download to see them.}


________________________________________________________________

The second part of experiment was :  experiment with yoke  where   pickup coil  was made out of
 two independent windings winded on one half of the yoke   one on the top of the other .
   picture :    https://overunity.com/19358/caduceus-coil-building-and-testing/dlattach/attach/189637/

Than two ends of  each individual winding were connected together  leaving two reminding ends  unconnected yet acting as an  output.
 that  by itself made   that half of the  yoke similar to pickup coil   that was used for the first  part of the test  with caduceus.
That means that winding  on this particular half of the  yoke  was alike the winding   on the pickup coil( outer coil)  on caduceus.

applies to  experiment with  yoke with some minor changes.

The main difference between:
-the two is that Yoke  had two half parts.
    picture :    https://overunity.com/19358/caduceus-coil-building-and-testing/dlattach/attach/189633/

-the ferrite ring was  not made from two halves

   picture :    https://overunity.com/19358/caduceus-coil-building-and-testing/dlattach/attach/189628/

_{Notice: when you press on these links  using Firefox browser -  that particular picture will be downloaded
instead of displayed so you need to open download to see them.}


There is another factor  important .
The yoke  halves  were  placed together but  allows to introduce  small gap between the halves from one side
or both sides.
-sometime that gap was regulated by placing in between  one or few pieces of  paper. to keep the space in controlled thickness.
similar technique was used commercially in flyback transformers in every TV using CRT tube called also cathode ray tube.
https://www.electronicdesign.com/content/article/21186397/why-have-an-air-gap

https://www.electronicdesign.com/markets/energy/article/21761319/mind-the-gap-and-improve-your-lowpower-flyback-transformer-design
The flyback transformer is very different from a signal transformer, and not making the distinction can lead to poor performance.
Actually, the flyback transformer is a coupled inductor and not a transformer in the true sense.

In the signal transformer, current flows in the primary and secondary windings at the same time, inversely proportional to the turns ratio of the windings.
In a flyback transformer, current flow is restricted to one winding at a time.

Interesting is that amount of people ready to experiment is very low here:
I was looking at my post

where I specifically say :

Please look at my precious post  before  reading this one.  Re: caduceus coil building and testing  « Reply #14 on: Today at 03:34:57 PM »

and  I see that only 20 people  viewed it.So the question is :
Who I'm dedicating my third day of  documenting  Lithuania Experiment to?
thinking about :
-cost of travel,
- fight  with custom in Lithuania  still under Russian  influence in  2011 when they saw weird to them looking content of the suitcase .
- time spend there  in that post soviet environment for an American from USA right after I returned from Tbilisi Georgia when
  I was poisoned  by some Russians along with Tariel Kapanadze.

The two trips together cost me several thousands  dollars than with paying the member of assassin crew to find more about these Russians.
The doubled  flight tickets because  some of that airport personnel in Prague was bribed by them.
Anyone of  you would go to such trip knowing that  he may not return  in vertical position from it?

 You expecting   knowledge and experience and real results from both the  Tariel Kapanadze
 Tbilisi Georgia Europe  trip and from Kaunas  Lithuania trip.
 and at best for free and delivered in front of your  nose  and at best today.
 for what?
 for some of some of your laziness?
 Is this what  Energy for Free  community is about?

Darwin's evolution stopped after his death 

In essence, sarcasm is easy (as is most anger, criticism, and meanness) while true, harmless wit takes talent.
A question I think you will not answer, not because you are Russian but because you  have no gods to  answer is:
Why?
Why Darwin's evolution stopped after his death?
Wesley

input is very strange because of the very low impedance there.
Collapsingfield

I  have problem  in  understanding- your problem with  application of your yoke.

I understand that :
- you have single coil winded on the yoke - means having two  wire ends and it  has small inductance.
  the permeability of the  ferrite  used  in this yoke is not known
  https://en.wikipedia.org/wiki/Permeability_(electromagnetism)
_________________________________________________________________
So I respond with some basic knowledge.


Difference between Inductive Reactance and Inductance.
An inductor: is a static two-terminal electrical component that stores energy in a magnetic field when electric current flows through it.
e.g: coil, chokes, or reactor.
it is physical component you can hold in your hand.
/difference-between-inductive-reactance-and-inductance/
Inductive Reactance (X_L) : is the opposition offered by the inductor in an AC circuit to the flow of ac current.
it is a process that exist in the inductor that depends from: e.g  frequency
https://byjus.com/jee/inductive-reactance-and-capacitive-reactance/
 
Now we adding ferrite to the inductor:

While using ferrite cores in inductors, we consider the following things-
 High saturation
High impedance
Fewer losses
Stability in temperature
Properties of the material

ferrite-core-inductor-losses-characteristics-and-applications

some time ago in the past we used  silicone alloy metal plates like here for low frequencies
also called the Ferromagnetic metal core for high energy efficient transformer. Ferrite transformer for switching power supply.
selective focus, shallow depth of field. https://www.wellpcb.com/ferrite-core-transformer.html
So you don't have to use  the sintered ferrite cores https://en.wikipedia.org/wiki/Ferrite_(magnet)
You can use plates.
_{Note:some discussion is here although  not  very scientific:
ferrite-or-iron-powder-how-do-i-tell-what-an-unknown-core-is-made-ofand is based on 13 years old data.}

So in regards  to frequency:
Inductors are just a coil of wire - in a DC circuit they do nothing. _{well in most  situations as sometime we deal with AC having offset  DC and so on.}
In an AC circuit the inductor acts like a resistor, the resistance changes with the frequency.
That resistance is now reactive and is called inductive reactance that adds into pure resistivity of the wire.
Capacitors are the opposite. In a DC circuit they block current. In an AC circuit the "resistance"( capacitive reactance) decreases with frequency.
When we add ferrite core  to the inductor than The use of the magnetic material ferrite core allows for more frequencies with minimal eddy current losses.
 but  particular type of ferrite  material can only handle limited frequencies

In regards to yoke :
By adding air gaps to these ferrite shapes, the cores can be used efficiently while avoiding saturation.
so in my  previous  comment  I  presented the two halves of ferrite Yoke with  air gap regulated by piece of paper.

Most of that ferrite Yoke  assembly is used  in form of transformer and should be seen this way.
Because reactance is  measured in Ohms it adds to real resistance of wire  even if it is  reactive "resistance"
That is why if you have AC relay and connect it to DC you may damage the winding or blow the circuit  breaker as in DC  you have no  reactance  whatsoever
and you dealing with pure  resistance of the wire .

self-inductance
is associated with the magnetic field produced by a current, any configuration of conductors
possesses self-inductance. For example, besides the wire loop, a long, straight wire has self-inductance, as does a coaxial cable. 
So imagine  straight piece of wire  50cm long horizontally placed on the table or vertically suspended
That piece  of wire not connected to anything yet  is a perfect 1/4 wave antenna .
A ham radio operator at 144MHz=2m band  transmitting  signal can see that in Near Field  this wire is resonating
and having voltage on it.
Depends from  how much power you transmitting and how close to the real antenna of the Transmitter at 2m band is that piece of wire
_{(- it means how good coupling this  coincidental  form of that particular transformer type has)}
you may be surprised that  suddenly  you have 2kW of power on that piece of wire
_{( if your transmitter gives  more than that)}
______________________________________________________________________________

input is very strange because of the very low impedance there.
Collapsingfield

Why do we use Ferrite Core Inductor? 

Using Ferrite cores in inductors helps to improve the performance of the inductors by
providing high permeability to the coil.
It leads to an increase in their magnetic field and inductance. Usually, the permeability level in the ferrite core inductors ranges
between 1400 to 15,000, depending on the type of ferrite material used.
Thus, ferrite core inductors boast of high inductance as compared to other inductors with air cores.
https://www.cosmoferrites.com/news-events/ferrite-core-inductor-losses-characteristics-and-applications

The effects of capacitance and inductance are generally most significant at high frequencies.
 Usually input impedances should be
high, at least ten times the output impedance
of the circuit (or component) supplying a signal to the input.

I hope it helps.
