Claim Text:
1. A magnetizing printer adapted to re-magnetize at least a portion of a previously magnetized magnet, the magnetizing printer comprising: a magnetizer print head configured to print one or more magnetic sources having a first polarity at one or more locations on a side of the previously magnetized magnet having an opposite polarity, wherein the first polarity associated with the one or more magnetic sources is substantially exposed at the one or more locations on the side of the previously magnetized magnet but the opposite polarity associated with the one or more magnetic sources is not substantially exposed at the one or more locations on the side of the previously magnetized magnet, wherein the magnetizer print head comprises a plurality of layers of a metal conductor that form an inductor coil, and wherein the plurality of layers have a hole extending there through, said metal conductor having a width between an outer perimeter of the magnetizer print head and an outer perimeter of the hole, said width being greater than or equal to a diameter of the hole, said magnetizer mint head configured to generate a magnetizing field having a first magnetic flux density in and near said hole and a second magnetic flux density elsewhere when a current is applied to said magnetizer mint head, and wherein said first magnetic flux density is higher than the second magnetic flux density.
