Abstract
A method of forming an annealed magnet includes positioning a magnetizing array ring concentrically with a ring of bulk magnetic material to form an assembly, the magnetizing array ring having a magnetic field defining directions for orienting grains of the ring of bulk magnetic material, placing the assembly in a furnace, and operating the furnace to anneal the ring of bulk magnetic material and grow the grains in the directions. A magnetic array assembly includes a furnace; and an assembly including (i) a ring of bulk magnetic material having grains and (ii) a magnetizing array ring concentric with the ring of bulk magnetic material, and having a magnetic field defining directions for orienting the grains during growth thereof in a presence of heat from the furnace.
