Patent ID: 8648681

Claim:
A method comprising: providing a magnetic print head including a plurality of layers of a flat metal conductor configured to produce a plurality of inductive turns about a hole, said magnetic print head generating a magnetizing field having a high magnetic flux density in and/or near said hole and a low magnetic flux density elsewhere when a current is applied to said magnetic print head; causing at least one of a magnetizable material or said magnetic print head to move to position said hole of said magnetic print head adjacent to a first location at a surface of said magnetizable material where a maxel is to be printed; and printing a first maxel into said magnetizable material using said magnetic print head to produce a first printed maxel at said first location at the surface of said magnetizable material, the first printed maxel being associated with a first polarity and a second polarity, wherein the first polarity associated with the first printed maxel is substantially exposed at the surface of said magnetizable material, but the second polarity associated with the first printed maxel is not substantially exposed at the surface of said magnetizable material.
