Magnets, motion and measurement

[Floor]

But I am thinking about this a lot.  Still working out in my head the best way to move the shielding magnet at exactly the right time.  I think I have that idea worked out but will need to make some prototypes to see what works best.

Take care,

There is no continuous motion in the devices I have illustrated on this topic. 

There are some rotation aspects to some design  that were posted in another topic. See below.

All motions and / or actions are start, completion of that action, then and then only then, does the next action begin.

There is No constant motion.

I am planning to build a device based on your rack design.  Shown in this PDF: Rack Action 3 complete.pdf
I plan to have some weight on the upper arm and magnet to return it to the start position after the shield magnet is back in place.  Then remove the shield magnet again to restart the cycle.

Since the tricky balancing and the extra power of the earlier design was not enough
I have switched to this. See the drawing. It is necessary to keep the gap to a minimum
to get maximum power. The domino sized ceramic magnets are too thick.
So I used 2 stacked Radio Shack ceramics with the hole in the middle to get
more repel power with less gap.

Where this logic is wrong is that when two magnets are stacked together they are stronger.....right.
So the center magnet will get stronger where the poles add (N + S) and appear to the other repelling where there is (N+N) as a single stronger magnet, So in the end it's a wash and the magnets stay separated.

It would work if steel was used for the center magnet but that also causes it to become harder to remove when the repelling magnets are closer to the steel.
Maybe the center magnet could be two thin magnets with a thin sheet of steel between them to reduce the adding effect.

I think IEC uses something along this line, where there is some steel between the repelling magnets. (laminated if you look close)

Lumen I'm not sure your are right. Is this head work or bench work?
The center magnet is sort of shunting the mag fields on both sides
of the magnet.

I should know in a few days....
