The embodiments of the invention generally relate to a novel magnet arrangement to further enhance the performance of the array. The new arrangement of magnets (for example, five configurations) can result in significantly much higher percentage gain in magnetic flux with respect to the largest magnetic flux of a component magnet, as compared to Halbach array configurations.
