Abstract
Magnet array structure includes a first linear magnet array and a second linear magnet array having a first and a second arrangement of magnets, respectively, in which the first and the second arrangement of magnets are repeated along respective lengths of the first and second linear magnet array. The first and second arrangement of magnets include respective individual first and second magnet elements arranged along the respective length of the first and second linear magnet array so that no net magnetic forces parallel to the length of the first and second linear magnet array result on the first and second arrangement of magnets, respectively. The first arrangement of magnets is offset from the second arrangement of magnets so that the first arrangement of magnets and the second arrangement of magnets partially overlap.
