Claim 10:
11. A magnetic assembly comprising:
a plurality of magnets arranged in a linear Halbach array having a strong side facing a first direction and a weak side facing a second direction opposite the first direction, each of the plurality of magnets shaped as a radial arc segment having opposing radial end surfaces, wherein an arc length of the Halbach array increases as the Halbach array extends along a longitudinal axis oriented perpendicular to the first direction and the second direction, each of the plurality of magnets having a through-hole defined therein extending from one radial end surface to the other radial end surface, wherein each through-hole is longitudinally aligned with a through-hole defined within an adjacent magnet; and
a ferromagnetic pin positioned within each through-hole to connect adjacent magnets, wherein the ferromagnetic pin has a size, a shape, and a magnetic permeability that facilitate a magnetic force between a respective pair of adjacent magnets in the longitudinal direction inducing a magnetic flux path through the ferromagnetic pin such that an apparent magnetic force between each pair of adjacent magnets is one of i) a repelling force less than 5 newtons (N) and ii) an attracting force.
