Abstract:
1. A method for producing a magnetic field emission structure, said method comprising: generating a magnetic field by applying an amount of current to an inductor coil comprising a wide metal conductor configured to produce a plurality of coil turns about a hole, said wide metal conductor having a thickness and having a width extending from an outer perimeter of said hole to an outer perimeter of said inductor coil, said width being substantially greater than said thickness, said hole having a first diameter corresponding to said outer perimeter of said hole, said inductor coil having a second diameter corresponding to said outer perimeter of said inductor coil, said second diameter being substantially greater than said first diameter; and exposing a location on a magnetizable material positioned adjacent to said hole of said inductor coil to said magnetic field to create a magnetic field source, said magnetic field source having one of a North-up polarity or a South-up polarity in accordance with a desired force function.
