Magnetic structure
Magnetic structure production may relate, by way of example but not limitation, to methods, systems, etc. for producing magnetic structures by printing magnetic pixels (aka maxels) into a magnetizable material. Disclosed herein is production of magnetic structures having, for example: maxels of varying shapes, maxels with different positioning, individual maxels with different properties, maxel patterns having different magnetic field characteristics, combinations thereof, and so forth. In certain example implementations disclosed herein, a second maxel may be printed such that it partially overwrites a first maxel to produce a magnetic structure having overlapping maxels. In certain example implementations disclosed herein, a magnetic printer may include a print head comprising multiple parts and having various properties. In certain example implementations disclosed herein, various techniques for using a magnetic printer may be employed to produce different magnetic structures. Furthermore, description of additional magnet-related technology and example implementations thereof is included herein.
