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. |

1. A magnetizing apparatus, comprising:
an inductor coil having a hole; and a circuitry configured for applying a current to said inductor coil to create a magnetic pulse having a sub-millisecond duration and having a flux density sufficient to produce a maxel at a location on a first surface of a magnetizable material comprising Neodymium, said magnetizable material having a thickness between said first surface and a second surface opposite said first surface, said maxel having an area on said first surface about said location, said maxel having a depth within said magnetizable material that is less than or equal to said thickness, said maxel having a magnetic flux density of at least 1500 Gauss as measured at said location on said first surface of said magnetizable material, said maxel comprising a first pole having a first polarity and a second pole having a second polarity that is opposite said first polarity, said first pole of said maxel being substantially exposed within said area on said first surface, said second pole of said maxel being not substantially exposed on said first surface, said first surface having a portion outside said area that is one of unmagnetized or previously magnetized to have said second polarity. |
