Abstract

A permanent magnet contains a rare-earth element R, a transition metal element T, and boron. The permanent magnet contains a plurality of main phase grains and a plurality of soft magnetic grains. The plurality of soft magnetic grains contain Fe. A cross-section of the permanent magnet includes a plurality of soft magnetic regions. The cross-section of the permanent magnet is parallel to an easy magnetization axis direction of the permanent magnet. Each of the plurality of soft magnetic regions contains the plurality of soft magnetic grains aligned along a direction orthogonal to the easy magnetization axis direction. The plurality of main phase grains and the plurality of soft magnetic regions are alternately disposed in the easy magnetization axis direction. An average value of width of the plurality of soft magnetic grains in the easy magnetization axis direction ranges from 20 nm to 5 μm.
