Abstract
A method for manufacturing a bond magnet includes providing a bond magnet composition including a magnetic material and a resin, extruding the bond magnet composition in one direction to produce a molded body while orienting the magnetic material in the one direction, magnetizing the molded body in the one direction using an axial magnetization to produce a magnetized molded body, and laminating the magnetized molded body to produce a laminated molded body including first magnetized molded layers and second magnetized molded layers. The first magnetized molded layers and the second magnetized molded layers are alternately laminated. A first magnetization direction of each of the first magnetized molded layers is opposite to a second magnetization direction of each of the second magnetized molded layers.
