Abstract
PURPOSE: To change the inclination of magnetic orientation and to improve magnetic flux density by putting rolls side by side which are formed by winding magnetic sheet meterial with magnetic anisotropy and then winding it to form a roll.
CONSTITUTION: Preparing anisotropic magnetic sheet material which is ferromagnetic in the thick direction by rolling a mixture of magnetic anisotropy treated scaly ferrite particles and rubber or synthetic resin to orient the ferrite particles in the rolling direction of the sheet, winding the sheet to form a roll, and then pressing a plurality of rolls between molds having a plurality of trapezoid recesses side by side to obtain hexagonal blocks 13. Then cutting off the blocks 13 into upper part and lower part, winding it on a shaft 10, fitting magnetization yokes on the centers of bases of cut blocks 13, and magnetizing to obtain a roll magnet.
