What anomaly?
It is possible to approach magnets or ferrormagnetic bar and then move them away by a different path, with a difference of forces between the two steps, suggesting that one could gain energy in a cycle. Lafonte does this here in a subtle way.
Unfortunately, as Smudge has already said, a force is not energy. Energy is the work of force, so you have to measure the force point by point on the path of the sliding magnets between the bars, then sum up the product of force and displacement on the whole path, then do the same thing for the bars that are moved away, and then you'll see that you gain nothing.
I remember many attempts of this kind, of course they never succeeded.
The theory is still right: the work in a potential difference, in this case the magnetic potential determined by the relative positions of the objects, does not depend on the path followed between the starting and ending positions, but only on the starting and ending positions. On a cycle, this work is therefore zero. This is true for all potential energies.
