First Claim
1. A magnetizer for magnetizing one or more magnetic field sources into a magnetizable material, comprising:
- a first magnetization subsystem, said magnetization subsystem comprising;
a magnetizing inductor, comprising;
a plurality of flat conductor layers; and
a plurality of insulating layers, said plurality of flat conductor layers and said plurality of insulating layers forming multiple turns of a coil, said magnetizing inductor having an aperture extending through said plurality of flat conductive material layers; and
a magnetization circuitry for applying a current to said magnetizing inductor to generate a magnetizing field having a high magnetic flux density in and near said aperture that is sufficient to magnetize said magnetizable material and having a low magnetic flux density elsewhere that is insufficient to substantially magnetize said magnetizable material;
a motion control subsystem for moving at least one of said magnetizable material or said magnetizing inductor to position said aperture of said magnetizing inductor adjacent to one or more locations at a surface of said magnetizable material where said one or more magnetic field sources are magnetized into said magnetizable material, said one or more magnetic field sources having a first polarity exposed at the surface of said magnetizable material and a second polarity not exposed at the surface of said magnetizable material; and
a magnetizer control system for controlling said first magnetization subsystem and said motion control subsystem.

Abstract
A magnetizer for magnetizing magnetic field sources into a magnetizable material includes a magnetization subsystem, a motion control system, and a magnetizer control system. The magnetization subsystem includes a magnetizing inductor comprising a plurality of flat conductor layers and a plurality of insulating layers that form multiple turns of a coil having an aperture and a magnetization circuitry for applying a current to the magnetizing inductor to generate a magnetizing field having a high magnetic flux density in and near said aperture that is sufficient to magnetize said magnetizable material and having a low magnetic flux density elsewhere that is insufficient to substantially magnetize said magnetizable material. The motion control system moves at least one of the magnetizable material or the magnetizing inductor to position the aperture of the magnetizing inductor adjacent to one or more locations at a surface of the magnetizable material where the one or more magnetic field sources are magnetized into the magnetizable material. The one or more magnetic field sources have a first polarity exposed at the surface of the magnetizable material and a second polarity not exposed at the surface of the magnetizable material.
