Hi.
As of 11.1.11 I started my new project of a motionless electromagnetic generator. I will be disrupting magnetic field of a permanent magnet placed within a mobius coil wound on toroidal core made from ferrofluid. This core material will provide almost no hysteresis lossess to a high voltage pulse and it will respond to high frequencies of switching carrying magnetic mometum along the N-S axis and at 90 deg. around the toroidal core... I'm going to make ferrofluid first and then I plan to construct the core's shell from fiber glass stripe and some resin to form multilayered laminate on a wax donut model...
The idea is as follows: when a mobius coil is not being energized the magnetic flux is focused within the closed loop core (4), fixed around a permanent magnet (1). When a mobius coil (2) is energized it creates a twisted magnetic field gradient around it and saturates the donut core inside (3) at 90 deg. angle. It affects the closed loop core in such a way that the field from a permanent magnet now has to find some other route. The inner part of a mobius coil (wires close to the permanent magnet) creates magnetic field of the same orientation as permanent magnet's field. So those two vectors add up an now the lines of force go through the core in the shape of a triangle with a powerful magnetic momentum, inducing voltage in the output coils (5) of that core. Then we stop the current flowing through a mobius coil and the system seeks equilibrium state finding the shortest routes to balance itself. Closed loop core's particles rotate back 90 deg., which induces voltage on the output coil (5) around the outer edge of a mobius coil.
It is not a Mobius coil. It is called Rodin coil, my bad...
I got fascinated with the simplicity of MEG type generators and I wanted to improve on that. I came up with an idea as how to overcome some of the shortcomings of T. Bearden’s solution. The prototype somewhat worked but the switching mechanism for redirecting magnetic flux was not efficient. So I left it for a while. Recently I got this brand new idea of redirecting the permanent magnet flux path. J.L. Naudin’s improvement on MEG was the introduction of thin N-S field across the core, at 90 degrees to the lines of force going through it, which effectively cuts off the magnetic flux path with much less energy than the original design. This cross-path flux stream blocking is used in US 4,006,401 Patent for example. At first I wanted a generator based on one permanent magnet only to make things simple. Looking at pictures of how ferrofluid sticks around a permanent magnet I realised that the optimal C shape core for closing the path between the poles would be a thick shell encasing the magnet. The volume of ferrofluid picked up from a bath by a permanent magnet indicates the proper volume of the shell type core for that magnet, meeting the requirements for closing the loop with minimal leakage outside the core. The cavity inside the Closed Loop Core, contains Rodin type coil fixed around the permanent magnet. It is not the ‘original’ Rodin design. It will be bifilar, but in the same direction (Tesla style for electromagnets). One of the purposes of this coil is to effectively magnetise a part of the shell core at 90 degrees blocking the passage of permanent magnet’s flux through its volume. Looking at the outside edge of the Closed Loop Core I have to deal with relatively thin wall (because of the distributed cross section volume at a given radius). Now, I am going to use the peripheral part of the Rodin type coil (only half circle part of outside facing windings) to influence the magnetic vectors in this area of space. I could achieve similar effect witch a standard toroid coil, (similar to ORBO) but in this solution, the Rodin type coil besides providing the effect just mentioned, creates a strong magnetic dipole in its centre, parallel to already existing field emanating from a permanent magnet. The coil should be wound in a proper direction to create magnetic pole of the same polarity as in magnet. This configuration of two like fields in the same direction will have now a greater magnetization potential in the N-S axis of a permanent magnet, than the magnet alone would have. So to sum things up, by pulsing the Rodin type coil we effectively create high magnetic resistance in significant area around a permanent magnet forcing its flux through alternative route (through the core connecting all the magnets in a loop). It is similar to the pumping of a heart. At this instant randomly oriented particles of ferrofluid, which retain no magnetization will align to this strong presence of a magnetic gradient in this triangle output coil core. The main power of this combined magnetic impulse will come from a permanent magnet and the current induced in those output coils will have negligible effect on the input current in the Rodin type coil. There is another set of output coils placed around each disruptor on the swiching section of the Closed Loop Core. Without the Rodin field present magnetic particles orient on the N-S axis again rotating back 90 degrees inducing potential In these windings. I am expecting some translational movements within the donut ferrofluid core of the Rodin coil. I am not sure of the effects it will have on this configuration. Hope it helps.
First of all - why ferrofluid ? What are it's properties ? BH curve ? Bmax etc ? You said you want to make it ?! How ?
You can read something about ferrofuild here: http://books.google.pl/books?id=oGAOHrG24NUC&printsec=frontcover#v=onepage&q&f=false (http://books.google.pl/books?id=oGAOHrG24NUC&printsec=frontcover#v=onepage&q&f=false)
In short it is the best material for the core in this case. The main advantage here is its magnetic properties and that I can shape the core the way I want.
There is a method of synthesising magnetite here: http://chemistry.about.com/od/demonstrationsexperiments/ss/liquidmagnet_2.htm (http://chemistry.about.com/od/demonstrationsexperiments/ss/liquidmagnet_2.htm)

In the hypothesis of the linear case, i.e when the circuit parameters such as permeability or magnetic domains are not modified by fields, fields superpose, they simply add (vectorially). A variable magnetic flux can't modulate a static flux.
Therefore static permanent magnets in a magnetic circuit with coils play no role for the dynamical functioning. Only the source of a changing field is concerned.
When we remove the permanent magnets and replace them by the same matter but not magnetized, the MEG functioning is exactly the same.
Quote from: wikipedia
http://en.wikipedia.org/wiki/Motionless_electromagnetic_generator
In 2001, Bearden predicted that the first commercial products based on the MEG would be "rolling off the production lines in about one year", and as early as 2002 claimed to have a prototype of the device that produced "100 times more power out than was input"
...
As of May 2008, the MEG was still not in production, and Tom Bearden claimed he needed about $11 million to develop it to a viable commercial form.
Nobody has built a functional MEG. Every body failed with the MEG and with related devices, even Bearden. Naudin was mistaken in the measurement. Bearden's MEG is a hoax. The beauty of its simplicity is only a trap for newcomers and for those more concerned by the desire to believe than by the knowledge and the facts.
I am positive that my device will work and the key here is the geometry. Shaping the field of a permanent magnet in this way will provide needed potential gradient at some distance at will...
"Shaping the field" will not allow for free energy because "shaping the field" needs work/energy to modify parameters of a magnetic circuit such as permeability, magnetic domains orientation, inductance... And if you don't modify magnetic parameters then you remain in the linear case where "shaping the field" summarizes to superpose another field which adds or opposes the first one, depending on the location that is considered, and is of no help in the energy balance.
Our mainstream scientific theories are not complete yet and sometimes they are far from the truth...
I have a background in electronics engineering and I know what I am dealing with here. Energy used for the short pulse to the Rodin coil will be recovered in the output coil around the disruptor, after the pulse because the permanent magnet wants all the magnetic domains lined up along the Closed Loop Core from North to South. In this scenario magnetic domains of the core section close to the output coil winding rotate precicely from 0 to 90 deg. back and forth, with minimal friction. It is like a pendulum swing type thing…

You must consider magnetic domains as ensembles of current loops of same orientation. All elementary magnetic dipoles are current loops, even the electron spin. When you rotate the magnetic domains, you must exert a torque on the loops therefore you waste energy.
And there are also many errors of reasoning with the Rodin coils, due to the neglecting of "real life" such:
- capacity between wire turns, which is very important when signals have high frequency components
- HF radiation for the same reason
- flux leakage due to the orientation of the turns whose the cross section is not perpendicular to the toroid core
- extra flux due to the fact that the turns have also to be considered as a whole single conductor along the toroid, leaving us with a field perpendicular to the toroid plane
and so on...
So if you really think to have found the holy grail, you should build a real setup instead of designing a pretty model. We need here engineering in electromagnetism, not in CAD software.
I will build it for sure. I am making ferrofluid now...
@kEhYo77
Please keep us posted with how your build goes. I'm looking forward to seeing the results of your experiments.

Because one picture is worth a thousand words...
Yep don't let the naysayers discourage you. Nobody and I do mean NO ONE can say for sure what will happen in a real world experiment because NO ONE knows everything about everything that can have an effect in a given situation. If you feel your theory is good than build it! Best of luck.
I built this today... It is a beta version ready for testing. It lights up 2 ><LEDs at the 2 output coils when 12V is applied to all 4 input coils at once. This indicates that the output core section magnetises and demagnetises while pulsing DC in one direction only, which is a GOOd sign! There will be strong kickback from 4 input coils when the magnet closes the loop after the pulse. What is interesting at this moment is that when input polarity is reversed it still lights up those LEDs...
Today I started building a new configuration. The one in previous post was my first try and I had to make few adjustments. I salvaged two more ‘transformers’ from broken PC power supplies. It appears that many of them use similar components, so I have enough identical core material to work with now. It is quite hard to rip apart the coils but it is doable. I came across 2 different shapes of core pieces: C and L. Both of them have little slit in the shape of a triangle, right where my DIY bobbin is positioned. I filled that with powdered iron mixed with epoxy to fill this space.
The input coil this time will be wound close to perfection when it comes to geometry. I will be using two layers of wires, 16 wires per layer to form 3D Tesla bifilar pancake electromagnet. I think that the best way to connect all those wires is to make 2 interleaved sections 8 wires per section soldered together for handling high current. So it is going to be two multi strand isolated cables per section making sort of a bifilar tape. I will have two such tapes obviously to make pancake coils. I predict high efficiency and quick magnetic field build up as a result of this configuration.
Today I was browsing through google patent database and look what I've found:
http://www.google.com/patents/US20120161917 (http://www.google.com/patents/US20120161917)
it looks like this one is based on my idea from Feb 2011, what do you think about it?
Hi Kehyo,
In fact, the patent application you found has 'strong similarity' to an even earlier prior art, the so called Bulgarian MEG which exactly includes toroidal or rectangular closed cores in the outside MEG columns. See this thread here with pictures:
http://www.overunity.com/4300/a-truly-overunity-transformer-meg/ (http://www.overunity.com/4300/a-truly-overunity-transformer-meg/)
There is a Bulgarian patent on it, applied for it in 2006, see here:
http://worldwide.espacenet.com/publicationDetails/biblio?DB=EPODOC&II=1&ND=3&adjacent=true&locale=en_EP&FT=D&date=20070630&CC=BG&NR=109554A&KC=A (http://worldwide.espacenet.com/publicationDetails/biblio?DB=EPODOC&II=1&ND=3&adjacent=true&locale=en_EP&FT=D&date=20070630&CC=BG&NR=109554A&KC=A)
(unfortunately you have to pay for your local patent office to be able to have it fully)
You could inform the USA patent office about your and this Bulgarian prior art (you may get help how to proceed at your local
patent office).

The US20120161917-patent requirement/application disillusionate me cause the inventor write about a 95-105% efficiency ( very good for a transformer and this power range :2-3W ,but ) not near the COP 2,5-3,.. from Valeri Chobanovs experiments !
An easy "MEG" as structural part from a motor concept showed this publikation,inventor Heinrich Kunel :
