Rimbald - halfring-magnets

[pemox1]

Forces are of course much smaller with a simulation in mm.But I think, more important are the directions of the forces!

Does anybody know, where to buy half-ring-magnets

Suggestion: Get yourself a suitable profile ring of steel/iron (pipe section, etc) and cut it into quarters, then place a block neo at each cut. I've made quite useful 'horseshoe' magnets with square section steel and neos. Might be suitable enough to test your idea .....

Piecing parts together to a ringmagnet causes gaps and these gaps are producing spikes.
Because there are no such ringmagnets around the world, I tried to remagnetize an axial-magnetized ringmagnet.Though I think power is big enough for ferrit-magnets, I receive no correct magnetization. There always remain areas with wrong magnetization.Maybe windings are not exactly.....note: handling with 600V and more than 2000A is really nothing for beginners!

mmmm 1.2 Megawatt (assuming single phase only) not that big eh???
