MAGNET MANUFACTURING METHOD AND MAGNET MAGNETIZING METHOD
A method for manufacturing a magnet includes (1) a step of preparing three or more unmagnetized magnet materials of which magnetization easy axes are oriented in predetermined directions, and adhering the unmagnetized magnet materials with each other to make an assembly, and (2) a step of applying a...

| description | A method for manufacturing a magnet includes (1) a step of preparing three or more unmagnetized magnet materials of which magnetization easy axes are oriented in predetermined directions, and adhering the unmagnetized magnet materials with each other to make an assembly, and (2) a step of applying a curved pulse magnetic field to the assembly to magnetize the assembly, wherein in the step (2), the unmagnetized magnet materials are magnetized into magnet blocks, and an angle θ (where 0≤θ≤180 degrees holds) formed by magnetization directions of at least a pair of magnet blocks adjacent to each other is in a range of 30 degrees to 120 degrees. |
