Ya, that's the problem. my thinking is that it's not a 1-1 alternation but
maybe 2 in one dir for 1 the other, and the magnets on the car body (which
would have to be a lot longer body to allow for more magnets) are staggered
so that a preponderance of magnets are always above the repulsive ones,
enough to counteract the partial attraction of the lower quantity of
attractive ones.

As it is now it settled, there seemed to be a bit of jerking from one
position to the next, IIRC.
