PROBLEM TO BE SOLVED: To provide a magnet which is magnetized in a manner that different magnetic polarities are placed side by side in an area with non-magnetized areas, and to provide a magnetizing method and a magnetizing device by which the magnet can be obtained. SOLUTION: A planar coil 1 is made close to an area which is optionally selected from the surface of a not-magnetized magnetic material 4 that is formed in an optional shape, and then the coil 1 is energized by a DC current power supply 2. It is magnetized in a manner that different magnetic polarities are placed side by side in the area with a non-magnetized areas in between. |
