A year ago, Kregus started this thread discussing his research into Tesla’s Hairpin Circuit here:

dR_Green (Simon Davies) of, J_Dove, blackchisel97 and others pitched in to lend their expertise and Kregus has brought his experiment to completion. He will probably continue to study it, but check out the results, which are exactly like Tesla described:

Here is a link to his page that lists all the parts, setup, etc. – everything necessary to replicate this yourself. This is a high voltage circuit so please only do this if you have experience or at least enlist the experience of someone who is qualified.

For further study, check out Jonathan Zerbin’s page on this topic:

At this year’s 2018 Energy Science & Technology Conference, Ken Wheeler, author of Uncovering the Missing Secrets of Magnetism, will be presenting on magnetism.

Ken Wheeler is an expert in Ancient Greek, Pali, & Russian and has worked for various governmental agencies as a translator. He was the founder of a popular website that focused heavily on the teachings and history of Buddhism with a heavy focus on the etymology of its related language. Ken is passionate about learning, exploring and teaching various subjects, especially magnetism. Several years ago, he released a free book called Uncovering the Missing Secrets of Magnetism, which is already in its fourth edition. This work was dedicated to some of Ken’s personal friends and associates, but also to those that have paved the way for the electrical sciences with clarity and that includes Tesla, Maxwell, Steinmetz, Heaviside and Eric P. Dollard. The book is available here: (3rd edition)

When Ken Wheeler first completed the first edition of his book, he offered to have me distribute it and give all the sales to Eric Dollard as a donation. This was a very kind and selfless offer and we appreciate it greatly. Although Ken hasn’t asked for anything in return, we encourage everyone to support Ken by giving him a donation to PayPal email:

Perpetual Motion Holder Origins

Mineral, Vegetable and Animal Life by Edward Leedskalnin
Mineral, Vegetable and Animal Life by Edward Leedskalnin

Ed Leedskalnin, known for his amazing construction marvel Coral Castle, is credited with inventing a “Perpetual Motion Holder”, which consists of a U shaped core with a coil on both sides that are connected in criss-cross fashion. There is an iron keeper that closes the gap and when a battery is connected to the two coils, the keeper stays magnetized to the U permanently. This causes an internal magnetic current to run in the loop perpetually and when the keeper is finally removed by force, the magnetic field collapses and it causes the coils to output electricity.

The image above is a book cover to one of Ed Leedskalnin’s books, Mineral, Vegetable and Animal Life, which has the Perpetual Motion Holder depicted on the cover.

The Perpetual Motion Holder works as claimed and it is easy to build. What is interesting is that it is normally thought that current has to be supplied to the coils in order for the metal to become magnetized and when the current is removed, the magnetization disappears. However, this is not the case as is easily demonstrated by the Perpetual Motion Holder.  Many people have had these devices magnetized for many, many years and no matter how long, when the remove the keeper, the coils output a pulse of electricity. It can be measured with a meter or you can see that it will light an LED, etc.

Einstein said that the key to creativity is to hide one’s sources and in this case, that is exactly what Ed Leedskalnin did. It was known that Leedskalnin was very studious and he examined much of the literature of his day regarding electricity, magnetism, biology, etc.  During this time, one of the most famous books on magnetism, which is still a valuable resource was first published in the 1840’s and spelled out the Perpetual Motion Holder, but with a very different name – 100% exact explanation of the results of the device.

Davis’s Manual on Magnetism was one of the first and most popular books that detailed this device and virtually every technically oriented scholar at Princeton in that day knew of it.  This is NOT the first reference to this device, but it is one of many from it’s time. There is an earlier reference and we’ll get to that soon.

Davis’s Manual on Magnetism – below are some pages from the book’s title page and the relevant pages for the Perpetual Motion Holder. Please read the comments in between some of the images:

You can see on page 75 above that image 126’s description is that of the Magic Circle – the original name for the Perpetual Motion Holder. If you have two semi-circles attached with a coil of wire  around a side of this circle and charge it, the two iron semi-circles with stick together. If you remove the electricity, they continue to stick.

Below on page 76, you see a variation of this with handles that two people can pull on to demonstrate just how strong this effect is.  And you see the details of its interesting properties:

“If the flow of the current in the coil is stopped while the armatures
are applied to each other, as shown in figures 50 and 51, they will still continue firmly attached; but if once separated, will not adhere again.”

Below, you see in Fig. 53, the classic “STRONG” type of electromagnet as used by Ed Leedskalnin and is apparently invented by Prof. Henry who is mentioned in section 132 at the bottom of the page. We’ll discuss Prof. Henry soon.

Above is an image of another variation of the Magic Circle, which is designed for much stronger variations. It is a hybrid between the original Magic Circle and the strong electromagnet with coils on both legs of the horseshoe shaped core.

Below, it says, “If, however, the armature is applied to the poles, and the flow of the current is stopped while it is attached, it will continue to adhere for weeks or months with great force, so as to be able to sustain one third or one half as much weight as while the current was circulating. But if the keeper be once removed, nearly the whole magnetism will disappear, and the magnet, if of good iron, will not even be able to lift an ounce. The polarity of the magnet will of course be reversed by changing the direction of the current.”

That statement reveals that some of the power actually is lost after removing the battery, but for the most part, it sticks until manually removed – or until electricity with the opposite current is applied.

So there you have it, the full revelation of the “Perpetual Motion Holder from the 1840’s. The mention of Prof. Henry is very important because not only is he the inventor of these stronger electromagnets that went way beyond what anyone had developed before, but he appears to also be the inventor of the Magic Circle.

Joseph Henry was a contemporary of Michael Faraday and independently discovered the Laws of Electromagnetic Induction but about on year after Faraday. The unit of measurement for inductance is named after Joseph Henry.

In some of Joseph Henry’s notes, which are documented in a book called The Paper of Joseph Henry edited by Nathan Reingold, we see the earliest mention of the Magic Circle. This book details papers by Joseph Henry from November 1832 to December of 1835, which are called “The Princeton Years”.

Joseph Henry’s Magic Circle

Clearly, the editor of the book had absolutely no idea what the reference to the Magic Circle meant, but now you do! And it was in Joseph Henry’s notes around 50 years before Ed Leedskalnin was ever born.

This is the origin of the Perpetual Motion Holder, what is was originally called and who invented it. Please give credit where credit is due. The next time someone tells you about the Perpetual Motion Holder by Ed Leedskalnin, please kindly refer them to this page.

Please understand that this is not intended to take anything away from Ed Leedskalnin’s very interesting work but rather to correct a common misunderstanding about the Perpetual Motion Holder.

If you want to know how to make a simple one, this is one of the simplest How-To videos you can find:

The operating theory behind what maintains that magnetism is a whole other topic, but suffice to say, there is a magnetic current that is put into circulation around the loop. Many conventionally minded people do not believe in magnetic currents as they think a piece of metal that is magnetized only has a static field that just sits there. My opinion is that they are wrong, but that is another story.

Many years ago, John Bedini and I were discussing toroidal coils and he shared with me his belief that there is a magnetic current that is always in circulation around the ferrite core. The question then is how do we tap it for energy production? We did not come to a satisfactory answer, but something along these lines is possibly happening with Steve Marks’s TPU (Toroidal Power Unit).

You can learn more about that at Rex Research here:

One thing you  might find very interesting is that conventional science has indeed discovered a never-ending perpetual electrical current in circulation in closed metal rings.

Here is a story about it:

Another story:

Abstract says: Quantum mechanics predicts that the equilibrium state of a resistive metal ring will contain a dissipationless current. This persistent current has been the focus of considerable theoretical and experimental work, but its basic properties remain a topic of controversy. The main experimental challenges in studying persistent currents have been the small signals they produce and their exceptional sensitivity to their environment. We have developed a technique for detecting persistent currents that allows us to measure the persistent current in metal rings over a wide range of temperatures, ring sizes, and magnetic fields. Measurements of both a single ring and arrays of rings agree well with calculations based on a model of non-interacting electrons.

Paul Babcock’s Magnetic Core Material

Paul Babcock discussed this core material a long time ago starting with an interview I did with him near the time of our first conference. You can search my channel for Paul Babcock and related interviews: Paul Babcock

This is a very simple and effective way to make a core for an electromagnet that has very fast switching times and this is important if you want the oscillatory transients to have the highest possible voltage – this is what most people call the “spike”.

The video shows an entire how-to on this method – it could have been a 5 minute video, but I decided to just show the whole thing to answer any possible questions.

Please visit for Paul’s presentations that disclose the workings of his motor and switching technology – his motor uses this exact same core material.

Professor Haralick to Present

Professor Robert M. Haralick
Professor Robert M. Haralick

Professor Haralick is a Distinguished Professor at the computer science department of the Graduate Center, City University of New York. He has been a professor in the Bioengineering and Electrical Sciences departments at UW (University of Washington) and is a leading authority on pattern recognition.

At the 2016 Energy Science & Technology Conference, Prof. Haralick presented on: Paramagnetic and Diamagnetic Field Experiments, Robert M. Haralick, Guy Obolensky and Loren Zanier. You can learn more about that presentation here:

Guy Obolensky is the one who recently passed and a post is made here about him:

At last year’s conference, Prof. Haralick presented on experimental protocols for measuring subtle energy changes in water. This is a very tedious process and most scientists get it wrong. We’re all fans of Dr. Emoto’s work, but when you see his presentation on Mind Over Matter, you will learn about the protocols that Dr. Emoto actually never considered:

If you’re a fan of water technology and believe it can be influenced by subtle energy, then this presentation sets the foundation for quantifying the effects.

At this year’s 2018 Energy Science & Technology Conference, Prof. Haralick will present part 2, which will explore some of his personal experimental results and will do doubt lay out the very protocols that were used.

Goodbye Guy Obolensky

Guy Obolensky
Guy Obolensky

Alexis Guy Obolensky was a long time researcher into Tesla related technologies. People who worked with him in the past on various projects include Jim Murray, Prof. Robert Haralick, Paul LaViolette, Susan Manewich, and many others. I had the honor of corresponding with him periodically by email and knew his health was failing – he was working on a machine that he hoped would rejuvenate his body.

He died last month on January 9th – here is a copy of his obituary:

OBOLENSKY–Alexis Guy – “Guy”, of Sloatsburg NY, died on January 9th, 2018. Born in Chicago on March 3rd, 1929 to Prince Michel Alexeievitch Obolensky and his wife, Kathleen (nee Trask, of Lima, OH). Guy was an inventor and experimental physicist, well known for his research based on the work of Nikola Tesla. Guy is survived by five children, Michael, Alexa, Nina, Anna and Helena; and four grandchildren. A memorial service will be held at 2pm, January 16th at Saint Mary’s Episcopal church, Tuxedo Park, NY.


Here is a post by Guy Obolensky’s niece or nephew, which will give you more insight into what kind of person he was and what he was involved with:

Some of Guy Obolensky’s work is discussed in Dr. Paul LaViolette’s book Secrets of Antigravity Propulsion.

His work with magnetic fields was a part of Professor Haralick’s presentation Paramagnetic and Diamagnetic Field Experiments.
