3D-printed Magnets: How can you produce a magnet with exactly the right magnetic field?

3D-printed Magnets: How can you produce a magnet with exactly the right magnetic field? Today, manufacturing strong magnets is no problem from a technical perspective. It is, however, difficult to produce a permanent magnet with a magnetic field of a specific pre-determined shape. That is, until now, thanks to the new solution devised at TU [...]
