Take the nail and touch the magnet crosswise with the pointed tip of the nail over the center of the face so the nail contacts only half of the magnet pole. Compare the amount of force it takes to pull it away. It's noticeably less.

Now take the nail and place the point of the nail in the center of the magnet pole, but this time hold the nail vertical to the magnet like you are going to hammer it in. It takes a lot less force to remove the nail.

In Ufo's video, look at 2:46, as the rotor magnet passes the stator at the top.

So, if one was to terminate the ramp to a point. Say, ending at the middle of stator magnet. The ramps "hold" on the rotor magnet would be diminished by geometry, even though the magnetic induction force is the same, as in the nail example. It's all in the geometry. Big heavy induction at the beginning, with gradual release using two forces. Decreasing distance between ramp and stator which maintains the pulling force past mass center, and shrinking mass through geometry which minimizes the release forces.

My next test,

Randy
