Re: Adjustable Magnetic suspension?
OK I watched the video. From what I saw in the video...
It looks like they are flipping the polarity of small regions of ordinary-ish macro-scale magnets, with mm-ish levels of granularity. I suspect a similar result could be created by gluing together lot of small magnets (hexagonal bar magnets perhaps).
They aren't actually printing out magnets.
The arrangements they create don't strengthen the total field of the magnet, but they are able to concentrate the flux density in local regions (at the expense of the flux density everywhere else).
Congrats to them for creating what appears to be a macro-scale version of the magnetic medium and the read/write head of a Winchester disk (a computer hard drive).
The process, and the behaviors of the patterns they are creating are slick; and the prices of their products are low enough for Jane and Joe Doe to consider buying some to play with.
Can they really create any desire force vs distance behavior they want (in two finite-sized "magnets")? I'm not so sure physics will let them create *any* behavior I might imagine ... The YouTube guy said that, not a company rep.
Will the company be profitable? Good question. Time will tell.
Will their stuff be fun to experiment with. Definitely.
