When I went to New York some years ago, I received four pieces of advice from a Texan gentleman philosophizing in an Irish Bar. The first three nuggets of wisdom he gave me were the vague kind of advice you’d expect e.g. ‘always have an out’, but the last one, in contrast, had a laser-like precision: Magnets, he said if you figure those out they’ll have a statue of you in Times Square. Fast forward to the present day, and researchers at TU Wien in Vienna have mastered how to control magnetic fields by using 3D modelling design methods and a 3D printer. No fuss. No fanfare. No statue of them in Times Square (yet).
“A magnet can be designed on a computer, adjusting its shape until all requirements for its magnetic field are met,” explains Christian Huber, a doctoral student in the 3D print of polymer bonded rare-earth magnets, and 3D magnetic field scanning with an end-user 3D printer project.
Magnets, how do they work?
Much like the...
