PURPOSE:To concentrically position a roll-shaped magnet and a magnetization yoke, and its apparatus in the magnetization mechanism, of the roll-shaped magnet, wherein the concentricity of the magnetization yoke with the magnet can be adjusted easily, an operation which makes the gap between the magnetization yoke and the magnet definite can be performed simply and their relational position can be fixed surely, with good accuracy, in order to magnetize a prescribed magnetic force on the surface of the roll-shaped magnet. CONSTITUTION:When two split magnetization yokes 8 which can be moved mutually to their separation directions are bonded to each other, the position of the magnetization yokes 8 is set before a magnetization operation by using a reference roll B whose standard shape is the same as a roll-shaped magnet C as an object to be magnetized except that it is provided with a roll part 1 which can be substantially fitted closely to a cylindrical magnetization space formed of their yoke faces 10. Thereby, the roll-shaped magnet C and the magnetization yokes 8 are positioned concentrically. |
