Helmust Goebkes magnet motor

[solinear]

This looks like every other geometry-based magnet motor - it will hit a parity point and stop dead.  As for degaussing - I have a large number of 1/2" cube magnets and a handful that have been used in opposition quite a bit and don't notice much difference between the ones that have been used in opposition and the ones that haven't been.  You could probably measure it with a gaussmeter, but I can't notice it much otherwise.

I've just noticed...
If you have a look at Steorn's PM Orbo concept:

, it looks almost the same as Goebkes's one.
Should work.

hrmmm I do not see the relationship per say other then it is an attempt at creating a magnetic motor...
