Claim 0:
1. A magnetic assembly comprising:
a plurality of magnets arranged in a Halbach array having a strong side facing a first direction and a weak side facing a second direction opposite the first direction, the plurality of magnets comprising a first magnet and a second magnet positioned adjacent the first magnet, the first magnet having a first surface and the second magnet having a second surface adjacent the first surface, at least one first cavity being formed in the first magnet and extending inward from the first surface and at least one second cavity being formed in the second magnet and extending inward from the second surface, the first and second cavities being aligned along a third direction perpendicular to the first direction and the second direction; and
at least one ferromagnetic pin positioned within the at least one first cavity and the at least one second cavity to connect the first magnet and the second magnet, the at least one ferromagnetic pin having a size, a shape, and a magnetic permeability that facilitate a magnetic force between the first surface and the second surface in the third direction inducing a magnetic flux path through the at least one ferromagnetic pin such that an apparent magnetic force in the third direction between the first surface and the adjacent second surface is one of i) a repelling force less than 5 newtons (N) and ii) an attracting force.
