Abstract
A method of processing an anisotropic permanent magnet includes forming anisotropic flakes from a hulk magnet alloy, each of the anisotropic flakes having an easy magnetization direction with respect to a surface of the flake and combining the anisotropic flakes with a binder to form a mixture. The method further includes extruding or rolling the mixture without applying a magnetic field such that the easy magnetization directions of the anisotropic flakes align to form one or more layers having a magnetization direction aligned with the easy magnetization directions of the anisotropic flakes, and producing the anisotropic permanent magnet from the layers having the magnetization direction such that the anisotropic permanent magnet has a magnetization with a specific orientation.
