An idea that has been in my garage for a few decades.
Shielding the unwanted pole of magnets using flux shielding mechanisms to provide perpetual motion in a rotary device.
The best revolution number acheived to date from an itial spin of 10 rpm.
is seven (7 complete turns of mechanism.after initial spin up.
Any body interested in my achievement to date?.
Hi Psyd,
How did you shield your magnets?
Prometheus Effect
Created a monopole by use of rare earth magnetic shield. Commonly available metals are fused as an alloy in 2 to 6 ratio to stop hysteresus of the metal causing excessive drag, but as stated in a previous post it comes to rest after seven revolutions.
( My machine is called as such has four contr rotating sets of vector spaced "arms " holding the shields and flux gate modules.
Hello
did you spin it at 10rpm first, still little confused about this. How are you making this flux gate. My best record is 8 mins running then stopped some years ago. Like to know more.

Greetings everyone!..
I have an idea too... (who doesn't).. I'm new @ this.. I've checked other forums but they are too personal.. This one seems more open-minded than the others.
I've already did some 3-d drawings of mine, but I need a simulator.. A 2D simulator will do.. one that can show me what's happening with the gears and the magnet & shield position. I have a 3DStudio but don't know how to use it. As I said, a 2-D mechanical simulator will do!..
Any ideas of a free, simple one?
Thx!
I was first attracted to the idea of magnetic shielding in the 80's, but shelved my drawings when I realized no material was available with the properties necessary to shield magnets. Around six months ago I stumbled across a reference by Tom Bearden on a Symetrical Magnet Motor. Here it is:
http://www.freeenergynews.com/Directory/Inventors/Bearden/SymmetricalPermanentMagnetMotor/index.html
Then, around December 2004 I bought a sheet of Mumetal from Physlink. Mumetal can be cut with scissors and is highly permeable to magnetic flux. I tried every permutation I could imagine to shield the approaching like poles, but to no avail. The problem is that Mumetal is also attracted to magnets, hence, the age old problem of breaking past the gate.
Best of luck,
Howard
Making a magnetic 'monopole' I assume is much like
creating a 'single side magnet', which involved arranging
several magnets in such a way that the flux gets
'rerouted' according to a planned path...
I don't think this is really creating a monopole, nor
magnetic shielding, but rather just smart flux rerouting...
Which does not mean it can be very usefull.
I'll attach a pic of an example rerouted flux path.
Kind regards,
Koen
Hi All,
check out this Halbach array :
http://www.matchrockets.com/ether/halbach.html
Stefan,
yes, that is almost exactly what I'm talking about.
I hadn't seen that site before, but toying around with a number
of magnets it is very easy to figure out that something like
that works.
In the case of my eaxmple there would still be some flux on the sides of
the magnet array, whereas there is as good as none in the case
that is shown on that site. The flux 'direction' or polarity is different
in both cases, though. But the fact remains that that is what I
was talking about.
Thanks for adding that link! It's good to have an observant
monitor. ;-)
Oh, and of course, in my last post in this thread, I meant to
say "That does not mean it is NOT usefull", instead of
"... it is usefull". Sorry about that, I was a bit too quick on the trigger. ;-)
regards,
Koen
i think some pc speaker magnet configurations may appear similar to a monopole in one speaker i found 2 magnets strapped with brass coated steel there was a solid disk on one side then a ring magnet on the other with both north ends attached to the steel with glue, although the magnets are quite willing to fight each other to stay on the steel, the steel piece then has a protrusion going through the ring magnet the result is a south magnet with a very strong north center.
just an observation that may be helpfull :)
Stefan,
I think it was the halbach array that got me thinking about the smot. The idea of twisting the field, so to speak, to allow the magnetic influence to shift and let the ball or roller leave without any problems.
It might work.
The major problem I'm having right now is trying to mold a circular track to the rollercoaster formation of magnets I have built up. It's easy enough to build a straight track, but I need to be able to manipulate a circular track so as to experiment with height and distance between magnets.
Howard
Hi
try harden steel like a saw blade. I believe it is the harding process that does the trick.
perhaps you could consider
pyrolytic graphite

Sometimes, what you need can be found ready made in a scrapped
piece of equipment. Can you give any specific details of the track
you need? Presumably, the circular track MUST be non magnetic.
could it be a an hard wood? It could be turned on a wood lathe
very easily by any craft wood turner.

I was trying some experiments that showed promise for shielding. I figured it was just a mechanical problem. When I saw that simple pieces of steel (like a bread knife) would shield a rare-earth magnet I started trying to find a way to move the shield over the magnet as closely as possible without touching it ( using bearings of some kind ). The closest I got was a chunk of steel attached to an old hard drive spindle. When the shield got close to the magnet it shot above it and wanted to stay there. So I attached an elastic band to resist this. I found I could get very close to equilibrium, i.e. it took very little force to move the shield into place and back (exposing the magnet). I'm almost convinced this could lead to a shield that takes less energy than the attraction of the magnet it shields. It takes a lot of time experimenting though.
Hi rrintoul,
Your solution sounds interesting. Could you share some more details? i.e. what distance is the shield able to cover? how does the surface area of the shield compares to that of the magnet? what size has got the magnet, is it also from a harddrive? etc.
If you could make a photo from your setup it would be the best but of course only if you wish to do so.
Thanks
Gyula
Thanks Gyula,
The shield naturally wants to cover the entire magnet. The elastic band is tensioned enough that it tries to resist this attraction and uncover the magnet. The magnet was from a package of rare-earth magnets from Lee Valley Tools. It was the 3/4 inch circular magnet. I don't have the pieces assembled anymore after my move to New Zealand, but here is a crude picture.

Reade
I think that some kind of rolling bearings to either side of the magnet so the shield slides just over but not touching would resist the attractive forces better. I think that would scale better and allow for a very strong magnet. I just couldn't find parts to do that.
The shield itself was just some bracket I found that was less than 2mm thick. From what I read the larger / longer the shield is in relation to the magnet, the better it disperses the magnetic forces.
Hi Reade,
Thanks for the drawing, it worths a thousand words :)

Yes I understand and agree, otherwise the shaft + its bearings holding the shield piece should be made very robust to withstand the huge forces involved.
Maybe a U shaped shield could be also be considered, I think, also with rolling bearings.
I 'borrowed' the U shaped shield idea from the LEMA setup (Low energy magnetic actuator), see Steorn patent drawings here
http://v3.espacenet.com/textdoc?DB=EPODOC&IDX=US2006066428&F=0
you may have seen it.
Thanks again,
Gyula
I hadn't seen that link from Steorn. Very cool! I wondered if magnets in a row like that would help slide the shield. It looks like it. I can't wait to hear Steorn's next announcement early next month.
Thanks Gyula.
Reade
My own experience with how close I was to getting the shield on/off so easily coupled with the fact that it looks like Steorn's using a similar approach actually makes me start to think they might not be a hoax after all. :)
You've probably seen this video of a guy trying to replicate Steorn's LEMA:
http://v3.espacenet.com/textdoc?DB=EPODOC&IDX=US2006066428&F=0
It's really good, especially at the end. So now I'm getting really convinced of what Steorn's doing. In Wikipedia it says Steorn claims that patent is not related to their big news but that would fit perfectly with trying to throw people off the trail. Because if you can turn a permanent magnet on/off with less power than the exposed magnet can produce then that's all you need to prove you can make an over-unity device.
Hi Reade,
You accidentaly gave the Steorn patent link instead of the video link.
Well, it is possible they deny on purpose that their device includes the LEMA concept but I think it is a 50% chance. There are so many unknown magnetic phenomena to be explored...
In this Forum you can find several topics on Steorn, like this one dealing with the LEMA concept:

Thanks Gyula. I think I've seen all the relevant forums now from this site. Ya, the video in that forum was the one I was talking about. Two things I noticed though - I heard that Shaun said his was a permanent magnet acting on a ferrous metal. That's consistent with what I tried, because you don't want that side of it to interact with the shield. In the video Craig uses magnets on both sides. Also, in the Steorn patent the shield is as close as possible to the magnet whereas in Craig's video the shield is pretty far away. Since the magnetic field drops off so quickly, you don't have a lot of distance to play with, so putting the shield that far away from the magnet loses you a lot of power.
Reade
When the shield is really close to the magnet it makes it so much harder to move the shield. That's the crux of what Steorn has accomplished I think. By experimenting with the width of the shield and the placement of the row of magnets you try to find an equilibrium like I did with the elastic band, so it's possible to move the shield with low energy.
