Working magnetic engine

[MarkE]

The field strength varies from the ends to the middle.  There is a potential energy minimum and given time and freedom to move the horizontal magnet will find it.  Devices such as Howard Johnson built would overshoot the PE minimum point due to inertia.  The right combination of inertial and friction would allow his projectiles to run through his gates and stop some distance away.  The trick with such devices, as with SMOT and SMOT like devices is that it always takes more energy to return the projectile to the initial starting point than could ever be extracted getting to the stopping point.

Thank you

The center magnet instead travels an oval path and never leaves the field of the larger magnets.
It is pushed to the right on the lower path and left on the upper path.
Because both ends of the center magnet are exposed to the large magnets, the net attraction to the large magnets is near zero.

Looks like the plan to me.

Spend 50 dollars and build an instrumented test bed to see if your ideas about magnet interactions actually work.

A system like this can be modified or altered as necessary to examine magnet-to-magnet interactions, to see if any such interactions actually produce the  _gain_ in KE which would be needed for self-running.

You must not sell ideas if you want be good man, not egoistic man. You can only sell you work (some hand made for example things), not ideas.
