Magnets, motion and measurement

[lumen]

@ Floor,
That is an interesting video!
I tested this in the simulator and found amazing results.
It seems the center magnet set causes one of the outer magnets to loose all the force against it while the other sides force is greatly increased.

I tried both ceramic and neo's with the same results, but the neo's were obviously way stronger.
This may be in fact the key to getting something really powerful operating.

Hi Lumen

Cool
  congrats

Broad polar faces, facing each other makes a broader path for the
magnetic fields (lesser field density during the interactions).
Too great of a density within the fields tends to lessen the effetiveness of the
shielding / shunting.  Some kind of saturation phenomena, I think?  I think also
that this may be    ONE    of the reasons that the shielding, when done in
attraction modes of output, behaves not as well / differently.

Some pictures from my attempt to build the device shown in Floor's pdf.  I still need to get the other track mounted and then the track coming in from the right to shield and unshield the opposing magnets.  The magnets are ceramic and will be super glued to the aluminum end pieces on the track.  I have used a lot of my Dad's machinists tools I inherited from him to make sure everything is perfectly square and true.  The two bearings on one side and one bearing on the other side seem to make a very solid device that can still move easily.  And there are two bearings on the bottom of the track with one on top to control motion in that direction also.

I am working on this pretty slowly because of a couple of major home projects but will from time to time post updates as I get farther along.

Take care all,
Carroll

It looks like you have 3 bearings for the lateral (counting the Pinyon gear), and three for the vertical.

Nice progress !

Thanks.

There are actually 3 bearings for the lateral besides the pinyon gear.  The 3rd is hidden behind the top bearing in the middle picture.  You can barely see it just to the right of the block of wood the top bearing is mounted on.
