Magnetic OU principle, You should really take a look at this !

Thanks Butch,
I was thinking about making a pendulum rig, and your drawing gives me some ideas.
One of my ideas was to have the steel elements push a lever, kind of like a person pushing a kid on a swing, the "pushing hands" would be a repelling magnet. Problem is, somtimes these types of systems can get stuck. Have you built anything like this yourself?

I have been able to confirm the basic "Separation" effect using Ferrite beads instead of washers.
I slipped 4 beads onto a carbon fiber rod and brought the rod between two attracting ceramic magnets, 1/2 inch gap.
The bead stack expanded from 19mm to 28mm when brought between the magnets.

The beads I used fit the rod perfectly, slid very easily with virtually no wiggle.  I won't be able to test energy ratios
or  if "OU" until I build some kind of real rig.


Parts Used
4 Ferrite beads Part #FB-43-2401 from Amidon Associates CA USA
1 Carbon Fiber Rod .198" (4.98mm)  X 24" Midwest Products
2 Ceramic Magnets 47x22x9 mm  Home Depot
2 small 1/4 inch thick pieces of acrylic used as magnet spacer for clamp
1 Small C-clamp 3" inner jaw, cast iron

Can you tell me with the beads separated.. how strong is the force that spreads them apart?  Can you push them down?

Thanks,
Jason

The beads can be pushed down with your baby finger. But as you can see in the photo, there must be at least enough force to lift three beads against gravity. I will see if I can measure the actual force it takes to force them together.  To do this properly, I will need to build a small test rig, which will take a few more days... Perhaps others here can shed some light on what core materials "separate" best. For some of my other projects, Metglas can't be beat, not cheap or easy to get though.

P.S.  For some reason, Amidon dosn't list weight or mass on their spec sheets, but here is their web site:  https://www.amidoncorp.com

I did a test using neo mags with steel washers (of which may have become saturated in the strong magnetic field).  My test was just to see how much force there was between the washers.  To my suprise, there was very little.  The atrraction force of the neo's to the washers was much greater than the seperation force between the washers.  How does one intend to seperate the magnets from the washers if the attraction is so much greater?
