<p>PROBLEM TO BE SOLVED: To obtain intense magnetism and the wide magnetism operating area, by arranging a plurality of the unit magnets having the same shape so that the polarity is reversed to each other, and forming the magnetic gap between the respective unit magnets. SOLUTION: A fan-type magnet 1 is the unit magnet having the fan shape. By assembling these magnets, the circular shape as a whole is constituted. Then, N poles and S poles are provided. The arrangement is performed so that the polarities of the neighboring unit magnets are mutually different. These unit magnets are contained in the case made of plastic. A magnetic gap 4 is formed between the respective magnets by partition. Furthermore, the shape of the magnet is not limited to the fan shape but can be the any shape. The shape of the case can be changed for the shape. Furthermore, a spacer is provided between the unit magnets without using the case, and the unit magnet can be entirely molded with resin.</p> |
