Abstract

PURPOSE:For the magnetization of magnetic poles with difference intensities, to make a cylindrical magnetizing yoke, provide a plurality of polar sections with different surface sizes on the inner circumferential surface of said yoke, fit coil windings whose winding directions are opposite to each other round said polar sections, and place a magnetic disc on the inner circumferential surface of said coil windings. CONSTITUTION:A magnetizing yoke 1 is made cylindrical, and polar sections 2A- 2F are formed on the inner circumferential surface of said yoke 1 so that said polar sections 2A, 2c and 2E on one hand, and 2B, 2D and 2F on the other may have large and small surface sizes, respectively. Coil windings 4 are placed in the slots 3 provided on the both sides of said polar sections 2A-2F so as to have alternatively opposite directions to said polar sections 2A-2F. A magnetic disc 5 to be magnetized is encased in thus-constructed yoke 1, and current is supplied to a DC power source 6 connected to the led-out ends 7A and 7B of said coils 4. Thus, an asymmetric magnet disc can be obtained since ferro- and weak-magnetic poles are generated on the circumferential surface of said disc 5 facing said magnetic sections 2A, 2C and 2E on one hand, and at said magnetic sections 2B, 2D and 2F on the other, respectively.
