Abstract
Magnet array structure includes a first linear magnet array having a plurality of consecutively arranged first Halbach arrays and a second linear magnet array having a plurality of consecutively arranged second Halbach arrays. The first linear magnet array, from a first end of the magnet array structure to a second end of the magnet array structure, having magnetic flux orientations rotating in a first direction, and the second linear magnet array, from the first end of the magnet array structure to the second end of the magnet array structure, having magnetic flux orientations rotating in a second direction that is opposite the first direction. The first linear magnet array is arranged parallel to the second linear magnet array so that, between the first and second ends of the magnet array structure, the first Halbach magnetic arrays are linearly offset from the second Halbach magnetic arrays.
