Abstract
Magnetic field structures composed of stacked magnetic laminae that are magnetically oriented perpendicular to their planes and configured to cause a volume charge density and cancel the field effects of unwanted surface negative charges are provided. This arrangement causes a uniform volume magnetic charge density, which results in a magnetic field normal to the laminae. The stacked magnetic laminae magnetic field structure cancel the field effects of the deleterious unwanted surface charges because these surface charges are so situated that their contributions to the internal magnetic field mutually cancel each other, and thus they are no longer detrimental to the magnetic field created by the volume charge density. One embodiment provides a planar magnetic field gradient source structure.
