This article presents a fast optimization of a 2-D magnetic array using digital annealer, a hardware system which solves quadratic unconstrained binary optimization problems with massive parallelization. The magnetic-array structure, which is used for a vibration energy harvester and a planar motor, is optimized so that the induced voltage in coils placed above the array is maximized. A novel structure of a planar magnet array without the non-magnetic region is obtained as an extension of the Halbach array.
