Basic Principles of Over Unity Electromagnetic Machines
A Scientific View into the World of Free Energy from Electric Charges and Magnetic Fields
by Jovan Marjanovic, M.Sc.
Johann W. Goethe said that the biggest secrets were the open ones. You look at them but you do not see them. The same is true with the electromagnetic field. It is known fact that after switching off an electromagnet, its magnetic energy will be returned back to the circuit, usually as a spark. What was missed is the fact that the magnetic energy performed work by attraction of an iron bar and didn’t consume itself. This work, minus heat losses inside the circuit, is free energy or over unity energy.
The goal of this book is to unlock the secrets of over unity and to teach people what is over unity and how it works. The reader will learn basic ideas of making new ultra efficient electric motors and generators and how to improve existing patents which use permanent magnets.

Here is the first feedback from a person who read this book.
interesting book, Januar 09, 2012
By Pierre H.G. (Spain)
I ordered a few days ago, impeccable and fast delivery from Serbia.
Although I do not think too much about unity, this book deserves to be covered.
Interesting facts, ideas in search of free energy ..

Basic Principles of Over Unity Electromagnetic Machines, January 24, 2012
By Jean-Yves (France)
Yes, I comfirm: \"impeccable and fast delivery from Serbia.\"
I have just only read 4 chapters but this book seems great.
You are not overloaded with too complicated and useless equations.
Yes, it gives some maths but only just very mathsNot too much maths but enough. Obviously the author knows what he is talking about.
The English is simple and clear.
These 4 chapters have put in order and clarified some of my intuitions. In my opinion: it is a must read for any average \"Over Unity\" researcher. It will avoid pathetic trials and errors.
Morality: I have just ordered a second copy (for a gift). :) )

Mr., February 13, 2012
By Von Ives (USA)
Having been involved in magnetics research for over 35 yrs., I can say that this is about the best book I have seen on the subject matter in my opinion.
That an author with his academic credentials would even bother to consider the subject, much less write a book about it, is highly contrarian!
That he very well covers the problems that have to be solved with what evidence is acceptable is commendable. The examples of attempts to solve the problems, though not all-inclusive of course, demonstrates more than just academic treatment.
I do make one exception though. One of the examples cited is of one Daniel Quale machine. In communication with him to furnish acceptable physical proof of his claims, he was not only not cooperative, but down right hostile and belligerant for being asked to do so. Not very credible nor professional in my view.
There are a few language translation errors that do not take anything away from understanding the content. A book treasure!

Sorry but this is, at least in theory not true!
When an iron bar is attracted to an electromagnet the impedance of the coil increases, and the magnetic field gets stronger.
This induces a voltage in the coil that opposes the current applied.
This might still be OU because now the magnetic field is stronger we can extract more energy in it's collapse, but there is a catch.
Imagine 2 examples, in one case we have a coil of 500 turns with a steel core, we pass 1 amp through the coil and in doing so generate a magnetic field.
As the magnetic field is established we pay for it in impedance.
We then turn off the current and with it the magnetic field, the magnetic field again resists any change and so it increases the voltage we had been applying, the faster we try and cut off the applied current the greater it will fight back.
In theory we get out from the collapsing magnetic field as much we invested into it (minus radiation resistance) provided we give the back-emf a circuit to flow in.
Now imagine a second scenario, we take an identical coil on an air core and establish 1 amp, this coil has a much lower impedance being air core so we lose less energy in establishing 1 amp, but we also have a weaker magnetic field.
Now let an iron core be attracted to our air core electromagnet, as it is attracted we gain kinetic energy, but we pay for it too in increased impedance, as the magnetic field grows due to the iron creating a stronger field it will induce a voltage into the coil that opposes the applied voltage.
This seems like it might be ok at first blush because we get all the energy back when the field collapses right?
Nope!
What happens is that because the current was at the full 1 amp level when it encountered the impedance the voltage drop created by the iron core is induced on a wire carrying more energy.
So lets say that in the first case the coil felt an average of 5v of opposing voltage from the coil for 1 second and during that time an average current of say 250ma, this means it cost us 5v * .25 amps= 1.25 watts to establish the magnetic field.
In the second case the iron being attracted generates say the same 5v (actually minus the air core impedance we already had to may for) of voltage drop but it does it to an average current of 1 amp, so 5v x 1A = 5watts we had to pay for.
If you look at it we have just found why hysteresis works, the delay in magnetization of a core for whatever reason causes a loss of energy due to the fact that by the time it becomes magnetized there is a greater current flowing and the opposing voltage is working against a greater current.
I fooled myself with this concept a few months ago so that is why I can so easily dismiss it.
Of course Free Energy has also been noted by similar setups but only because they operate outside of the known laws of physics, it isn't as simple as attracting a magnetic rod.

I do not know what you meant by saying it cost s 1,25W or it cost us 5W we had to pay for.
We have to pay for nothing except for heat loses. Opposing voltage and voltage drop will return energy back to circuit.
Histeresis loses are also turned into heat loses. Author already excluded heat loses.
If we used superconductors then there would be no heat loses at all.

Strong research material, September 24, 2012
By Georgios V. (USA)
I was looking for some validation on my own experiments. The book gave me allot of materiel in one place to use for supporting evidence on a patent of my own. I did not know how far many people had come and how close my research was to many others. Soon I will be a contributor to this book and will be combining several principles into one new practice and thanks to the book itself it will be easier to show prior art and prior principles and their sources. Like many inventors we all stand on the shoulders of giants and we add to their original genius. I will ask Mr Marjanovic to become an SME for my company as soon as the first product rolls out. Keep up the good work! You have no idea what a resource this is to simple garage inventors.

By Nenad S. (Serbia)
This is a very good book for people who believe that the laws of classical physics are outdated and who wish to experience a different point of view. The basic assumption is that readers should have a sound knowledge of electrical engineering if they wish to understand and accept that which is written in the book. At the end of the book, in order to remove the last remaining skepticism in readers, a grade school example of one simple over unity motor should have been presented. People usually believe in what they see.

Mr.Marjanovic's "Basic Principles of Over Unity Electromagnetic Machines" is a great book. It increased my understanding why overunity is possible to demonstrate with tabletop models. I built two devices listed in the appendix. Now I grasp why my Bedini motor behaves the way it does. I hope the author will offer a second edition with lots of photos of working machines. I would like to contribute to it!

Electric vehicle company owner, February 28, 2013
By Brian Berrett (USA)
Read this book twice now and I consider it an indispensable tool for any serious engineer or designer who has ever looked into the possibilities of "free-energy". The examples and technical references are practical and fairly easy to understand. Mr. Marjanovic speaks in common-man language and presents a very convincing case of how one could build a "over-unity" machine in his own garage. I have been chasing the "free-energy" genie for over 15 years now and this is the best book I've seen on the subject, by far! I Highly recommend this book to ALL serious researchers in the free-energy field, as well as ANY engineer who has any interest in generator or motor design.

Down link is an early paper of Mr. Jovan Marjanovic. The book has similar title, but is different.
It has much more details, figures, new ideas and explanations. The paper was primarily based on other people's work, but in the book there are also some ideas author checked for himself.
