Abstract

A magnet and a method of forming the magnet are provided. The method includes forming a slurry comprising magnetic powder material and binder material and creating raw layers from the slurry. A magnetic field is applied to the raw layers to orient the magnetic powder material in a desired direction, and each layer is cured to form another layer on the most recent cured layer. The layers are attached together.
