I just remembered I have done the experiment Jack is talking about-there is one problem with repulsion and shielding you can't get around.
- when the shield is leaving from between two magnets in repulsion-the attractive force is double when the shield is about half way out-hence you gain nothing.
- if the magnets are not perfectly centered with the shield one magnet will repel the other magnet through the shield.
I have done this many times and cannot come out ahead, but I think this "C" shaped shield and the steorn configuration might work. It's always about millimeters, everything has to balance perfectly.It's a bitch in every sense of the word.

I have heard someone say that opposing magnets will keep their magnetisim without significantly weaking for thousands of years (at least about neodymium magnets). Is this true or not.

I'm not sure which one weakens the magnetic field, that should be determined :P IF you're looking for an attraction method, this may work.

There maybe some issues with my drawing regarding how harsh the cam should be.. but i'm bad with paint :P
its just a basic idea...
***EDIT***
The side view has an error, the LEMA w/ shield shown needs another magnet inside, (this is inline with the design on the patent, I just forgot to draw the other magnet)

Honestly I do not know, It's a 50/50 split from what I have read, some say yes ,some no. On the quantum mechanics end they say yes, the magnets will weaken, the domains get disoriented over time, I tend to believe this theory more than the others,my neo's are getting weaker the more I experiment. They are 1" round x 1/2" thick N40 and I can tell they are getting weaker in just 6 months of playing around.

unshield when the rotating magnet is slightly passed the fixed magnet.

Pull shield perpendicular to rotation (not tangential) and the motor will run either direction

Helps to have fixed magnet larger than rotating magnets.

You must use opposing fields.

Demagnetization is a funstion of the distance between the magnets and the amount of demagnetizing force - all magnet mfg's (the large ones) give demag curves/data.  The shunt helps correct demagnetization - just like on the old horseshoe magnets.

Long magnets are more resistant to demag as are the rare-earth magnets.

yeah JackFrost and I are on the same page here... this is (IMO) much better than the method steornquest is going with...

I used a cam on my previous design ( page 8 ), but gear driven would work well here too..(easier to build), where the gear replacing the cam is the same size as the gear controlling the shield...

Alcanadian,

Would you tell me how much force (just a guess or explanation) your magnets give? I'm trying to get a handle on the strength of various sized magnets so I will no what to order. How far away will one of your magnets repel another? How far away will they attract? I just want to get a feel for the power of neomydium because I have never played with one before.

I guess if my 2 cents count for anything I would say try to stick with magnetic attraction. It's interesting steorn is quoted as saying the machine will not deteriorate over time and he is using magnets, so my best guess is saying that he is using magnets in attraction or I think iron cores on the rotor. He does not specify anywhere how he makes power only how he switches the magnetic fields - hence the LEMA patent.
As well I ran a machine in repulsion briefly and it seemed to get weaker fast, no measurements so im guessing here.

Magnets will repel or attract as a function of the square of hte distance they are seperated.. so the short answer is infinitely :P

allcanadian, can you try to do something similar to the design on page 8?  I dont have any magnets..

A cam would be hard to construct quickly, but perhaps using 2 gears instead... 1 gear isntead of a cam, and the actuator tied to the wheel of another gear perpindecular to the cam

@vorlon

is there any consensus on what the shielding material is?? iron, mumetal, plastic??

could it be another permanent magnet as the shield

My neo's have around 35 lbs pull each, attraction is felt at about 1 foot, repulsion the same.
All I can say is they are absolutely insane, you cannot pull 2 of them apart with your hands, big strong men have tried and none have done it. If they are loose and come together even an inch apart you will understand these are serious dangerous magnets. They are really cool you just have to be very careful. don't let children anywhere near them whatever you do.

cheap neo magnets and holding cups:

leevalley.com

Look under "hardware"...

Cups shunt the opposite pole and make the magnets stronger - see this:

Can't use another magnet as a shield.

I think its pretty well accepted that they are using a mu-metal shield or something similar.
