The pic shows the elements used for the simple test. The bars are laminated steel with small neo's at the end covered with electrical tape. The small neo can be seen on the ruler. The paper adds a frictional resistance to any movement, you can feel the flux pressure at a couple of MM increments before the bar actually jumps.

@Chet,
Thanks, but not CRANKYpants anymore, now notaspicegirl, gotta love it!

@exxcomm0n,
Thanks for additional info.

Larry

Sorry Larry I can't see what this test is proving, for 1 your using different size magnets which means different strengths and ofcause you double the distance a magnet moves if it repels at one end and attracts at the other.
There is no wall showing because your not comming in from the side so your not seeing how the rods will truely react, again I can't see what your trying to show with this experiment.
Sorry and take care Larry

Ouuu thats purdy!

BATMAN ...HI ALL

Here is Mr. Quinns GRAVITY WHEEL DONE NO.2 !

3 DAYS AND COUNTING !

BATMAN HAS MADE A FEW WHEELS AND WHEN HE DRAWS THEM IN A CAD. PROGRAM THE BUILD HAS BEEN MADE.

first comes the build then the CAD. DRAWINGS.

MORE TO COME.........IT'S ALL FUN.........BATMAN.......SEES BATGIRL LETS TAKE A BRAKE A... F....HER.........

STAY TUNE..............BATMAN.

You have obviously been listening to Archie too long.

"Equal and opposite" doesnt mean a magnet will act equally in repulsion as it does in attraction, just like you probably can't pull a sofa as easily as can push it.

E & o means that two bodies acting upon on each other exert forces equal an opposite, respectivly.

Two magnets in repulsion repel each other equally and in opposite directions; you push on the sofa with the same force the sofa pushes back on you.

Equal and opposite.

PurePower,
yes, yes, we all know how you will take one's words and make them right for you, but wrong for the origional writer.
what I was trying to say was that there IS a difference between repel and attract.  This has been PROVEN time and time again.
as explained in this thread long before you showed up:

Why are attraction forces stronger than repelling forces? Shouldn't the magnetic forces be equal and opposite?

Magnets in attraction produce an increasing field strength in the gap between them as they approach, and therefore greater force. The reason is that the effective system permeance coefficient (PC) increases as the magnets get closer. As they approach, more flux lines flow from one magnet to the other, rather than taking a path from North to South pole of the same magnet. This causes them to act increasingly more like a single, longer magnet with a greater load line slope, increasing the value of Bd and decreasing Hd for both magnets. (PC = Bd/Hd)
 
Since flux lines cannot cross each other, the bucking magnetic fields of magnets in repulsion are compressed. Flux density in the radial component of the bucking fields increases in amplitude as the magnets approach each other, and more of their own external field (Bd) is pushed back into the magnets themselves, where it becomes part of the self demagnetizing field (Hd). Since Bd decreases while Hd increases, the PC value decreases as repelling magnets get closer and there is less external field available to create a repelling force. A repelling magnet arrangement can apply intense cross fields where magnetic domains have the least resistance to external influences, so some level of demagnetization may occur, depending on magnet geometry and the coercivity of the material.

a simple test for ya Purepower, and Rusty Springs,  grab the strongest neo's you have, and stick them together, now measure how many pounds force to pull 'em apart.
now take the same ones and try the same test with repel.  BIG DIFFERENCE.
I know that you both will have a explaination as to why this works like this, but the point is, there is a difference, and there must be some way to make use of this "magnetic imbalance"

Sorry dirt there wont be a big difference but as I said its hard to measure, if Dusties reading he maybe able to lead you to an experiment Butch L did that shows difference is strength between the two, he has two wood beams one on top the other, the one on top swivels and has an attracting magnet on one end and a repeling magnet on the other end.
On the beam that doesn't move he has two magnets on each end again one attracting one repelling, he swivels the beam on top it attracts into the attracting side pulling the repelling side close and sits there.
You would say the attracting is stronger because it brings the repelling in but then you get a piece of paper and place it between the attracting magnet, once you do this the repelling magnet pushes the beam away now the repelling is stronger then the attract because it pushes the attract away and out of its attracting mode.
There is videos of this on the net I just don't know where but Dusty knowing Butch may know where to find them, this was done along time ago and when I say along I mean more then 5 years ago.
Take Care Dirt
