This is simpler then my other design,

Simpler yet.........

how about an animation for your design?
here's some drawings of it going through it's motion
the red half circle is the magnetic hill and it starts at the top and gets closer to the bar's path, which has one magnet on each end. It only uses attraction. The small black circle is a rotating shaft.

It's a standard attraction hill, the magnets get closer and closer to the path of the passing magnet.
To calculate a lever it's force x Distance, so the long side is say 4" and has a force of 2, that equals 8, and the short side is D1" and F5 = 5. So the long end pulls it into the attraction even though it has less force. Most importantly it pulls it out of attraction, where the sticky spot usually is.
I'll do a side view
The "shaft" is not shown. can you read the typing in these? mabye it's a video card difference. :-\

oh the black thing above the top magnet is the bar.
Hi Buzneg
Been looking at this design and others and struggling still with your pictures.
Can you draw the circles/disks that the ramp magnets will be mounted on to give a bit more of an illustration. Sort of idiots guide to your idea.
Sorry for not getting it straight away but the idea is in your head and not so simple for thickos lke me LOL ;D .
Regards
Sean.
It appears to be much like a minota wheel but the magnets face up and not out... BUT I don't understand how the fulcrum moves still.
this is another above view. This isn't the same as my other idea but it works on the same theory-principle.
The red dot's are fixed magnets on a surface that's also fixed. they're evenly spaced, and rize up at you as you go from the top/long end to the bottom/short end. the bar has magnets or just metal on it, on each end. Only the bar a the pivote it's on rotate, and the bar slides through the pivot as it shortens to follow the magnetic hill.

Bingo!
I managed to understand your explanation on this setup except this last sentence:

Would you supply what is missing (is it an 'and' after the word bar?) and my question is how the bar would escape from the raw of the magnets? Also: what distance would the bar cover by sliding through the pivot? Could you sign that distance with two small lines in your picture or even better it would be if you could favor us to draw a second picture showing the other (end) position of the bar with respect to the pivot and the surface?
One more question: the pivot has no mechanical connection with the surface, right?
Thanks,

sorry I shoulda checked my post
what that means is, as the bar travels the magnetic hill, it rotates causing the pivot to rotate, it aslo slides into (trought) the pivot because the magnetic hill pushes it that way.
The pivtot is a solid peice that only holds the bar, because it has a hole through it, which the bar slides.
Theoreticaly it should excape the magnets on the "sticky" end of the hill by the other end of the bar, being attracted into the beginning of the hill. Why? because the beginning of the hill is weaker but it's on the long end of the "lever" (bar)
In this picture, it show's the beginning and the end, because as one end of the bar is ending the other end it beginning, the hill.

The pivot will need to be well greesed-up because when the bar is hanging out far on one end and short on the other it will cause friction, so mabye extend supports as part of the pivot out along the bar, to hold it better.

Thanks. Maybe a linear bearing between the pivot and the bar would ease friction, together with the supports, though it would make the setup more involved. Hopefully you may have the means to test this interesting idea somehow.
