OK, my apologies. I have tried a new thread, but it's almost impossible to get a useful response from anyone. I would just like to discuss this idea briefly to check if I am on the right track!

I forgot to mention the magnet specs: 9x9x10mm long Ceramic grade 8 blocks, From a website app, I get a field strength 1mm from the surface of about 0.1158 Tesla.

Here is the concept attached. The target is 220 V; I have 3 rings of solid copper coil of 220, 300 and 400 windings respectively joined in series. The cross section area is about 3 mm^2 with a very thin insulation, which I hope can handle over 25 Amps. These are embedded in the (blue) casing, 2...

Hi, I have the same question actually, but am still in the dark as to Faraday's proper application. Could I possibly add to this thread with a concept of my own, which may shed some light on the subject? I would like to add a drawing here, because the answer would really depend on the configuration?

Took longer to update my concept, but this is what I had in mind, more or less. A PDF is attached for your amusement! The internal diameter is roughly 4"/100mm and the entire device is about 515mm long, without stand 'feet'. It consists of a revolving magnetic array in an a high-strength...

Hi, thank you for your concern. I'm still working on the concept, but there seems to be too many unknowns. I think that if I can eliminate the unknowns one by one I can see if this thing is even workable! There are 3 parts to this design: the generator, magnetic bearing (if it can work!) and the...

Thanks for the feedback...at least there's hope!? Spinning is exactly what it should be doing, all the time (gyroscopic effect applicable here?) Must confess, I don't fully understand the DYNAMICS of what Earnshaw's is all about. What I certainly understand is that you cannot just repel one...

Thanks f95. I'll check up on Earnshaw's, but I have heard of it...so even if one were to place magnets around a conical rotor which basically centres the weight of the whole thing to a middle axis (since none of the magnets in the array can touch each other?), it still cannot work? Dunno if I...

oh, and of course the question is...can it work?

Actually, what I was really trying to check was whether the arrangement in the attached drawing makes any sense. The 'axial magnetic bearing' illustrated in one of your links seems to me like a strange combination of magnetic flux, but maybe this is the only way to configure such a bearing...

Thanks Astronuc, your assistance is much appreciated! I'll have a look and see if this will help. Seems to be a very shrouded subject though, since people understand so little about magnetic forces?

Hi, I am hoping to get some feedback on the following question please: Can permanent magnets, such as neo magnets be set up in a polar array configuration so as to act as a magnetic bearing? I have seen various examples of actively-controlled magnetic bearings that use finely-tuned computer...

Energy is never destroyed, but eventually it all ends up as heat as we all know. I believe (and am not sure) that since there is actually 'work' being done that eventually there is energy being spent. Compare for instance a fridge magnet stuck to a door: not doing any 'work', so it will probably...

Hi, I am investigating a different configuration for an inductance coil, is there a way I can send a pic here to explain?
