I migh sound negative but when I was reading through this website it looked a bit like free energy scams to me, "stick a rod into the ground and voila, bulb is lit". drawings of magnets with two poles adjecent to the same pole- when I was attending physics course our proffesor told us that magnet would rearrange so there would be 2 poles if we tried tricks like this.. I'd like to see the 'how it's built' before I can attempt to get rid of my scepticism..

Yeah, doing some googling it seems that if you for example glue two together in a NS-SN type fashion that they would either turn into a single magnet as you are describing, or if its unstable then the two fields will demagnetize each other over some time.

But having said that, there's probably a few openings for research in there where you can experiment with different field/magnet shapes, sizes and counts.

You could in theory make that with two solenoids sharing a core and inverting the electric field and make it work like a NS-SN joined magnet.

But I guess it would heat up fairly quickly, having to fight the force of the opposing S-S poles. Now I want to try it.

I'm not sure what they want to achieve with that. The logo looks like they invented magnetic monopoles, but otherwise it's just a lot of blabla.

Investor trap?

beneath the fancy graphics there's zero explanation of how these are manufactured, how they're constructed, or the magnetic field patterns. No actual deployments or demonstrated applications, just graphics. It's a 3-person company that "expects to begin testing of this exciting new technology early in the 2nd quarter of 2023".

I misread that as "a magnetic fluid orientation" and it made me wonder: could a torus of liquid or something like that be induced with a spinning magnetic field to replace mechanical motors for electricity generation?

Maybe a giant spinning mass of molten iron the size of a small planet?

magnetohydrodynamics (MHD)?

Maybe I'm missing something but this just seems to be a guy playing with magnets? In the "Demonstration of Ion Propulsion" video, he shows how the magnet "shoots" through the ring, but it's just the release of potential energy from forcing the opposing poles together in the first place. It's like those "permanent magnet rail guns" people post on YouTube. I don't see what's novel about it.

What advantage would this have over a rotary Hallbach array?

the idea is simple enough, use both poles of permanent magnets, unlike other motors that use only one side while alternating the polarity of the fixed magnets. Watch the little slow motion video, it is either a masterfull slight of hand, or evidence. the magic I believ is in harnessing modern compute and power control hardware to achive something that was long ago dismissed as wishfull thinking

No numbers: no data. No data: smoke and mirrors.

Did I miss the memo where we repealed ∇·B = 0?

Don't talk about it, be about it.
