Newton's Magnets

For me will be easier to use above drawer slides for the linear motion - they are very sturdy.

What are you building ?

Sturdy is good but low friction, low mass and especially not much Wiggle, are what is needed.

QUOTE  from Telecom
"It appears that on the outside there are two repelling magnets, and one magnet in between.
It is equally spaced, and attracts to one external magnet while being repelled by another.
The way I see it, attraction and repelling forces on the central magnet act in the same direction.
In this case, how they are being equalized?
(Its quite different from the case when outside magnets are synchronized through the
rack and pinion arrangement, where outside magnets are pulling each other in the opposite directions)."

"how they are being equalized?"

Your question is very much too vague.   
Your question is probably already answered some where in the those drawings and explanations.

Hi Floor,

I wasn't sure where you wanted me to post the video showing the start stop action of the rack design so I put it in the other thread.  Here is the link:
