Sounds very fascinating, I've skimmed through a couple of their pdfs but couldn't see, is there one that explains how they create them?

- jfoutz 11y agoin the youtube video below, they show shots of the hardware. I don't know what the material is. My guess is they have a print head that will generate a real strong real small magnetic field, they walk the print head over the base material reversing the field in specific spots. that's what it looks like to me anyway.
- deutronium 11y agoCheers, yeah it sounds like you're right "Multipole magnetic devices may be constructed from discrete permanent magnets, or by exposing heated magnetizable material to a coded magnetic field." - https://en.wikipedia.org/wiki/Programmable_magnet https://en.wikipedia.org/wiki/Programmable_magnet
- pbhjpbhj 11y agoThe patent doc linked elsewhere in the thread talks about two coils with opposite fields being used at the same time; only took a cursory glance though.
