RESONANCE EFFECTS FOR EVERYONE TO SHARE

[gotoluc]

Hi Michael,

welcome to the forum, this topic and the world of over unity seekers.

For being new to OU... I would say you have been doing your homework.

You are asking good questions and most I don't have answers for since I didn't try it yet.

I think the reason I didn't continue testing with the Avramenko plug is that the secondary was showing better results as far as handling a load (10 Ohms resistor) then the Avramenko plug was. So I just continued testing with that. This does not mean that the Avramenko plug is not worth researching, it is just the direction I took at that time.

There are so many combination to try that it sometimes overwhelms me   You will see once you get to start testing.

I cannot change the direction taken at this time but I will keep it in mind if I go back that route

Thanks for sharing your thoughts and all the best in your research.

Hi Luc, thanks for the fast reply.

If you found out that the secondary was performing better with the 10 Ohm load, can you remember how it was with the avramenko plug. Could you still measure any reasonable voltage across an avramenko plug with the load connected?

Anyway, I wish you all the best progress in your research. I will keep up reading and learning about this stuff and I hope some day to find time to follow up your work (perhabs being able to contribute something)

Cheers

Luc,

I am just taking some time to think about some of what has been discussed and I have been reading more about inductors.

What is taking place in an Inductors is not simple.

Below are some excerpts from one of the documents I have been reading.
http://www.g3ynh.info/zdocs/magnetics/part_1.html

Simple coils of wire are dispersive.
Dispersive in an electrical context, where a dispersion region is a frequency range over which permeability or permittivity is changing.

The term 'refractive index' is not much used in electrical engineering; but many will be familiar with 'velocity factor', which is its reciprocal.

This begs the question; "what has velocity got to do with inductance?" to which the answer is; "rather a lot". The traditional understanding of coils depends on the idea that they are effectively electromagnets, and that they have reactance because energy is stored in the surrounding magnetic field.

This picture is mostly wrong, even though it suffices at low frequencies. If we may take the liberty of using the word 'light' to mean electromagnetic radiation of any frequency; what a coil really does is to modify the refractive index of space in its vicinity in such a way as to bend light and force it to follow the electrical conductor.

All electrical circuits do that of course, but in inductors, the path is deliberately made long. Hence a coil is a waveguide or transmission line, which stores energy by trapping and detaining 'light' which would otherwise have made a much shorter journey.

The inclusion of self-capacitance into the lumped-component model gives rise to the prediction that a coil will still exhibit parallel resonance in the absence of an external circuit. This is indeed correct; except that, unless the coil is extremely long and thin, the actual self-resonance frequency (SRF) is considerably greater than predicted. This failure of the lumped component theory is mainly due to the onset of another dispersion-related effect; this time in which the apparent inductance declines (presuming that we adopt the view that the self-capacitance is constant) in such a manner that the SRF is pulled to the frequency at which the wire in the coil is very nearly one half-wavelength long.

     This time, there is no reprieve for the lumped element theory. The SRF occurs at the electrical half-wavelength point because that is the frequency at which a wave, trapped in the coil by reflection from the impedance discontinuities which occur at the terminals, arrives back at its starting point in phase with itself.

The pulling effect can be understood by considering the overall field pattern as the superposition (combination) of two waves, one traveling along the coil axis and the other following the helix.

At low frequencies, the axial wave dominates and the helical wave is forced to keep up. This causes the phase velocity (i.e., the apparent velocity) of the helical wave to be several times the speed of light.

As the frequency increases, the helical velocity falls steadily as propagation along the helix becomes increasingly important, but the change is smooth and corresponds to an impedance characteristic consistent with the lumped component model.

As the SRF is approached however, the scattering cross-section of the coil suddenly increases and the axial wave is overwhelmed. Hence the impedance characteristic deviates as the coil 'locks-on' to the half-wave resonance.

It seems to me that for anything unusual to happen in an inductor that it should occur at a low frequency where the helical wave was several time the speed of light.

[EDIT]
Low frequency meaning frequencies below the SRF of the inductor.

Thanks for that read, giving a very good technical explanation of what we are seeing in coils. Makes sense and puts a good visualization of the event.

But low frequency should have to be DC pulsing since with DC you will find many resonance points far below the single resonance point you will find with AC sine or square wave pulsing coming from a FG.

    This is a great site for explaining some of Tesla's work and theory.  It is all about inertial waves in an electrical circuit.  Suppose a wave induced in the outer periphery of the cone resonator.  As the wavefront progresses through the conductor media it encounters a smaller and smaller radius which translates to a higher and higher rotational velocity of the wavefront.  As this wavefront reflects at the inner core of the helice it then constructively interferes with inputted waves until the coil reaches resonance.  Now view the wavefield distribution as a velocity distribution.  Upon attaching the base of this resonator into a large electric field.  One can see that the inertial flow distribuition will expand into this field.  With the wave front  going slower and slower at increasing radi but always returning to the high velocity inner core where it is reflected again.  The resonation then becoming magnified.
