PROBLEM TO BE SOLVED: To provide the magnetizing apparatus and method of magnetized pulser rings for increasing magnetic force for magnetizing a cylindrical elastic magnetic member, and facilitating the centering of a magnetized yoke, and to provide a magnetized pulser. SOLUTION: A magnetized section 3a of a magnetized yoke 3 is set to a conical surface being slightly inclined to an axis center. The magnetized yoke 3 is inserted into a cylindrical steel plate 1 of a magnetized pulser ring 10, thus allowing the magnetized section 3a of the magnetized yoke 3 to adhere to one end section 2b in the axial direction of a cylindrical elastic magnetic member 2. |
