Abstract
A method for fabricating a non-planar magnet includes extruding a precursor material including neodymium iron boron crystalline grains into an original anisotropic neodymium iron boron permanent magnet having an original shape, wherein the original anisotropic neodymium iron boron permanent magnet has at least about 90 percent neodymium iron boron magnetic material by volume. The original anisotropic neodymium iron boron permanent magnet is heated to a deformation temperature. The original anisotropic neodymium iron boron permanent magnet is deformed into a reshaped anisotropic neodymium iron boron permanent magnet having a second shape substantially different from the original shape using heated tooling to apply a deformation load to the original anisotropic neodymium iron boron permanent magnet. The original anisotropic neodymium iron boron permanent magnet and the reshaped anisotropic neodymium iron boron permanent magnet each have respective magnetic moments substantially aligned with a respective local surface normal corresponding to the respective magnetic moment.
