Here is how to make this thing work every time!!!!!!

Take a piece of PVC pipe 4 X 1/2 inches in diameter by 1 inch wide, this gives you the right diameter for the outside, the inside diameter then becomes 3 X 7/8" inside diameter, now find some 1 X 7/8 X 3/16 inch cheap magnets at the hardware store, (cheap ones).

Glue the magnets around the inside of the PVC tube all North Poles facing inside, this gives you the big correct ring magnet.

Now get a ring magnet 2 inches in diameter by 3/8 of an inch, get a steel ball of 1 inch diameter. Stand up the magnet with the steel ball put the big ring magnet above this and get it to stand up when the magnet starts to fall it will start to spin.

Keep the angle right and it will start to speed so fast it will try to fly off the table, so it takes work to keep it up.

NOTE : The 4.5" pipe is BLACK ABS plastic

My Brother sat there for about 1hr after that "HE SAID THAT HE HAD AN IDEA FOR NEW PERMANENT MAGNET MOTOR BUT NOT LIKE HAMELL'S" I will keep you posted on what He makes as for Me I have MY own ideas.

Jerry share this with everybody so WE can finally get something done. We are running out of time.

Hi John!

Say, I tried that thing with Radio Shack off the shelf 1" disc magnets. The first trial was with a 4" pvc pipe with the magnets on the inside rim, using another magnet mounted on a 1" diameter ball and with another magnet mounted on a 3/4" ball. It did not even try to spin. I stuck a magnet on a plastic pen to see how strong the fields were and there was a good 1/2 to 3/4" gap from the inside magnet perimeter to a detectable repulsion.

So, went out and and picked up a 2" and a 3" fitting and tried it on both, using the same kind of magnets and the same bearings. It is in attractive mode and the ball will rock around a bit but does not spin more than about 180 degrees max before stopping.

I tried it with different pitch angles thinking along the lines of Beardens' regauging where you use a progressively higher intensity placement of magnets, but it simply slides to one side and hangs up at an angle. Strange...

Well, at least with the 2" pipe the magnet on the ball at least stands up. Perhaps it has to be on a glassy, minimum resistance surface but I tried that on a dining room table and it did the same thing, no prolonged spin.

I note in the picture that Hamels magnet is tilted which would cause a weak to strong attraction gradient because of the pitch, but without some inertia you are back to the old 'over the hump' problem that occurs with all perpetual motion machine great going down and part of the way up, but about 320-350 degrees, it needs a kick to make it go on over.

That is how the guy in Louisiana does his, he has an electric motor that helps it over, with a large enough mass and high enough speed, it can get some power generated.

Well, I am disappointed so far and can't understand what would make it rotate unless;

  • 1) there is an inherent spin in magnetic fields
  • 2) there is a field interference between two magnetic fields that produces a rotation
  • 3) it has a gradient field with a kicker (what you suspected as the wobbling of his hand)

I think Hamel realized this also and that is why he resorted to the cone under cone schemes using the tilt of the cone in its attempt to restore balance....that tilt is 'just enough' to serve as the kick it over the hump that it needs to start another revolution.

Well, I'd really like to report that I saw the thing work and did it myself using something off the shelf, when other people do the same thing, then its I'll post your report and see what happens, maybe someone can duplicate it and/or report back on the 'trick'......seeya!

This must be done just like I said, it will not work until It's done like I have done it, I have already tried everything You have done. The geometry must be correct or the magnetic fields will not do the two particle spin.

Once again the big ring must be 4 1/2 inches in diameter the magnets must be 1 inch X 7/8 X 3/16. All North Poles must face inward when this is done this will give you an inside diameter of 3 7/8 by 1 inch width, this gives you the correct gate, the ring magnet must be 2 inches X 3/8 thick South POLE facing upward. this unit must be in attraction, the magnetic field being strong will only hinder you.

The Big Ring magnet has only 14 magnets inside it the 15TH magnet is left out, The unit must be placed on a Formica table to take advantage of the reduced friction.

I took the unit I made to My Brothers house where a birthday party was going on all the kids are 7 years old every one of them once shown could do it. My dad who is 73 years old even did it. My Mom is the only one to have a hard time keeping it up.

I guess I should make you one and send it to you so it will work, I asked Gary to make a film of Me doing this and I will send it to you. Jerry the Geometry of this is very important you can't make changes it must be done just like I said.

The Radio Shack Magnet you are talking about means you must have a different Gate to match the ring with the ball, The one inch ring magnet must have a gate of 2 1/2 inches in diameter or it will not work.

Report on what I have said let them dispute me and I will win when you see the video I send you.

I also have sent you a .GIF to use you can put all the dimensions in the proper place, I also will try to set up another page with this on it, I wish I had a way to make a AVI of this. Can you help?
