Gravity magnetic lever wheel working in WM2D (could this work in reality!)

[ooandioo]

   Hello Andi
   I clicked on the rectangle (magnet)then went to world, magnet field into the work place, then set two rectangles on a plastic floor and watched as they repelled each other then adjusted the setting until they repelled close to the real magnets I have. I am not sure of the accuracy of the simulation, but am encouraged by the design.
    I hope this helps
     Thanks

But that is for the whole working place I think. How did you set this magnetism to the magnet rectangles only?

Greetings, Andi.

  Hello Andi,
         

But that is for the whole working place I think. How did you set this magnetism to the magnet rectangles only?

That was and is my concern with wm2d, I made everything else out of wood and plastic at first so only the magnets were effected by the field. Then as I worked with it a little more I changed some of the material to steel and standard and it sill worked the same.
    When I was working with the magnet settings selecting pair-wise they attracted and on field they repelled.
   I have worked with some magnets and by shielding the upper part of the field with another field I can duplicate the slide and push without the sticky part coming into play I think.
     Thanks again

I also found out this while playing with your setup. Perhaps it can be shown with a 3D setup. Someone out there who has WM3D or Interactive Physics?

You said you enabled friction for all the objects? The constraints (the axles and the slider) are where the friction needs to be, because
there are no objects directly sliding against other objects in this sim. If your pin and slider joints are frictionless, I could see how it would run forever...

I only have the evaluation demo of Working Model so I can't open your file. Are the exact dimensions/values you used important? If not, I may try to replicate it myself.

Also, I noticed the odd shape of your stationary magnets. They appear to have one L-shaped pole that is larger than
the other pole and covers two perpendicular faces of the magnet.

Does such a magnet exist?
Could it be manufactured?
Does the simulation not work with ordinary flat bar magnets?
