Magnet motor idea - again.

[Low-Q]

Hi,


Here is the first experiment with ferrite magnets (Speaker magnets). Stationary magnet has a stack of three (Two big and one small) magnets with a few washers between as spacers so the moving magnet (same size as the middle magnet in the stack) can enter the notch/pit freely.
As surface I have two aluminium plates.


Notice where the neutral position is for both attraction and repel mode.

The hands are there just to align the magnets. When the magnets initially repels, the position where they are neither repelling or attracting is so delicate, only friction on the surface stopped the moving magnet from flying away. You see that I move the stationay magnet maybe 1 mm at max, which was enough to trigger the powerful repelling action (Which is pretty amazing itself). This last video is only showing how the assambly works.


To be continued ;-)

Vidar,
When you have the moving magnet so it repels, if you move it too far, does it pull into the slot?
It looks like this might work!

Try using non-magnetic spacers, and make two stacks like this: 
NS-spacer-SN-spacer. You will have to glue it so it stays together since the like poles are facing.
Flip one over so it's spacer-NS-spacer-SN . Now see how they interact when approaching sideways like you are doing.

I've found positions where the stacks are not in contact, but are stably magnetically connected. I call this a non-contact trailer hitch. It's a stable position of the magnets where they aren't touching but don't want to get closer together or further apart.
