Abstract
A magnet array is disclosed comprising a plurality of polyhedral magnets arranged in a Halbach cylinder configuration, the centers of individual ones of the plurality of polyhedral magnets being arranged substantially in a plane in a magnet rack, the plurality of the polyhedral magnets at least partly enclosing a testing volume, and comprising a first plurality of polyhedral magnets arranged in a Halbach cylinder configuration and a second plurality of polyhedral magnets arranged in a non-Halbach configuration. In another aspect, a magnet array is disclosed comprising a first subset and a second subset of polyhedral magnets having different coercivities. In yet another aspect, a magnet array is disclosed wherein a subset of the centers of the individual ones of the plurality of polyhedral magnets are laterally displaced from a nominal position in the magnet rack to counteract a magnetic field gradient of the magnet array.
