Proof of concept - perturbing a static magnetic field

[karl]

Stefan,
habe das Buch mal bestellt, kann man auch f?r 2,95 bei Amazon bestellen.
Suchen nach Skilling Networks in INternationalen B?chern, der Mann ist gut, schau mal in google, ein altes H?schene wie auch Aspden, ein Neucreator und Besserdenker, kein Sturkopf.
Er wird wegen seiner leicht verst?ndlichen Schreibweise gelobt, es scheint ein Mensch zu sein hat eine in einer Rezession geschrieben, denn er Schreibt mit Herz und Einf?hlungsverm?gen.
Wenn das Buch bei mir ist (Fernleihe kann einwenig dauern) poste ich den Umfang um die Formel, das interresiert mich selbst mal, was mit der Formel genau gemeint ist:
vielleicht eine simple Oszillatorbedingung bei Gleichspannungsspeisung (selbsterregung nach Schalterschluss).
Ist aber auf alle F?lle interessant f?r mich.
Kann das mal jemand in ein konventionelles Bauteilemodell (SPICE) implementieren?
Die Bedingung ist ja mal sch?n ?bersichlich und kann leich in einem Reihen RLC ausprobiert werden.
Nur die Quelle ist unbekannt und kann leider nur experimentell (so wie fr?her fr?her fr?her...) empirisch und intuitiv ermittelt werden, vielleicht gar keine unbekannte...
Gru?

Karl,

Are you refering to a simple  SERIES connection of L, C, and R?

Can you post more info, a schematic perhaps?

EM

Hi Em,
yes an R&T&L, Book is ordered, you can buy it at amazon.com fore 3 dollars.
One of the best Autors for absolute beginners, have a look at the vitae at google, an high ghost.
I'll tell you in this threat what happens at this point of view after receiving the books.
...looking forward for you...

Hmm? The Energia patent is interesting. There are some features that appear common to a number of other devices.

I can feel the frustration in this thread ? I don?t want to add to that but at the same time I think a step back may be needed. There are assumptions being made that are unfounded and some things are being overlooked.

First here are some questions that the patent raises:

1.   The effect works with or without a permanent magnet ? but the only reference to magnet type talks about an iron cobalt alloy. That is most unusual as it?s not a common alloy for modern commercial magnets. The patent is recent and yet is goes out of it?s way to mention iron cobalt and makes no mention of the most common types -- ceramic or Neodymium based magnets. Why?

2.   Why the very strange earth point? ? as described the whole drive system will float high on a pulse? and it?s a floating potential dependant on the impedance of the coils and the pulse current. They make a particular point of the earth arrangement in the patent. This sort of detail would normally not be worth of comment in a simple system like this.

3.   The pulse sequence is complicated ? in a quick reading of this thread I don?t recall seeing anyone get it right -- apologies if I am wrong. Given the data in the patent there is a sequence of pulses applied to a first coil. These pulses alternate between two values which are at least 50V apart? eg, 200, 200, 300, 300, 300, 200, 200, 200 etc.   with the number of repeats at one level being random from 1 ? 3 (preferentially). This sequence is followed at a very short time interval by the same sequence x 2.5 amplitude on a second winding. So in our example above the second winding would be pulsed with 500, 500, 700, 700, 700, 300, 300  However the effect will work without regular period and with any amplitude ratio as long as the second set is larger and higher than 50V above the first set. Why? ... could this be due to the equivelant frequency increace of electrons with voltage (energy = frequency) or due to an expanding collective wave or due to a non-linear pumping of the second wave in the wake of the first?

4.   The use of two windings allows for very short delay intervals between the pulse trains ? a delay that is less than the pulse duration. This implies that it is the pulse front that is the effective factor here. Furthermore they say that wider spacing of coils ? or more interleaved coils allows for a wider time between the first and second set of pulses. This implies a wave front that is traveling in one direction. ? They do state that a single coil can be used but they imply that the delay between the two pulse streams is too short for this to be practical. Although they also state that an effect can be seen with a single coil and a single pulse train -- but they never once state that you dont need pulses of at least 50V difference in the pulse train.

5.   They give no hint as to why random amplitudes, phase delayed pulse streams or the two level pulse stream is required. Therefore we can?t make any assumptions -- It could either be essential for the function of the effect or it could be to prevent runaway oscillations destroying their devices and equipment.

6.   They state that the device generates magnetic field that is thousands of times greater than the permanent magnet. They give no details of how they measured this. We cannot assume it is a magnetic field they are measuring ? although they clearly measure something that behaves like a magnetic field. Even a microsecond pulse of a 2000 T magnetic field will literally explode both the magnet and the surrounding coil.  ? a simple example? try hold two neodymium magnets side by side such that their north and south poles face the same way ? the repulsion is great. The magnet experiences these self repulsion forces internally which contributes to the fragility of high field magnets.  Likewise ? a pulse of 2000 T field will induce a current spike and a physical force that will explode any surrounding coil? so either they start out with milli Tesla field strengths or they may not be dealing with a magnetic field but something else/new that has some characteristics of a magnetic field.

Whatever the peculiarities of their devices testing is well within the reach of everyone. The description of their motor embodiment only uses 1MHz pulse repetition with 100ns pulse widths. This is quite slow and well within the reach of modest solid state designs.

I am still studying the motor aspects of the patent and may come back with more comments later.

Cheers

Mark.

Many thanks for your comments Mark, much appreciated.

There are some references on the internet that suggest Iron-Cobalt alloys make good cores for electromagnets, and are also used in power transformers.

In 3). you say that "This sequence is followed at a very short time interval by the same sequence x 2.5 amplitude on a second winding.".

To clarify, I believe the sequences are interleaved, the second sequence starts within a few say nanoseconds of the first sequence starting. This is reinforced in the patent's description of the pulses if using only one coil. In the motor section they quote a delay of just 10 exp-13 seconds between the start of the first and second sequences - the delay due to stepping up the voltage x2.5. in a transformer.

Your observation on the earthing point is very interesting - I hadn't noticed this at all.

If coil1 gets a pulse of 400V this will float both coils to 400V ?
Whilst coil1 is still on, coil2 will pulse with 1000V (x2.5).
Does this mean both coils now float to 1400V ?

Coil1 now turns off, causing a back EMF of say 800V, which will appear on top of the 1000V of coil2 which is still on ? ie. 1800V. ?
Coil2 turns off, causing a back EMF of say 1600V, which will appear on top of the 800V BEMF ?


So what does pulsing a pulse translate to in terms of spinors ?

Cheers Bob.
