Quadratic magnetic gate

[Low-Q]

The clue I believe is how to balance between the start point on next gate and the finish point from previous gate. In a single magnetic gate, one doesn't worry about where to put the moving magnet, as one can easily put the magnet close enough to the gate in order to get a forward motion. If several gates are placed after each other, one have to consider the magnetic field created by the previous gate, and how this influence on the start point for the next gate. How close is it possible to arrange the gates after each other, and how should the path be arranged in a closed loop?

If one successfully can make the moving magnet to pass three or more gates in a row, and accelerate for each gate, I believe it's possible to close the loop. The bad thing is that this gate seems to repel the magnet in the opposite direction if the starting point is to far from the gate. So balancing the distance between the gates is very critical - if it ever will work.....
