The engineer in me wants to know how they print these things. From the speed and the fact that they're doing it on rare earth magnets, I'm thinking that they somehow reorient the fields inside an existing conventional magnet. The vague descriptions on the Correlated Magnetics site seem to support that notion. But I have no clue how they can do that on the scale they're working with...
Got mine in the mail today. Very cool. If you get them, don't just stick the square ones together. If you do, let me know how you get them apart.
ReplyDeleteWhy are the square ones especially difficult? I've gotten magnets apart in the past by "sharpening" one edge of an aluminum sheet, then tapping it to force it between the two magnets...
ReplyDeleteI'm still waiting for my rotate-to-latch-and-unlatch magnets...
