Magnetizing device for magnetic particle inspection of wheel

摘要

[Problem] To provide a magnetic-particle-inspection magnetizing device capable of sufficiently ensuring that the density of magnetic flux extending in the circumferential direction of a wheel in the space around both sides of the wheel is adequately provided from a boss to a rim of the wheel. [Solution] The present invention is a magnetizing device (100) for magnetic particle inspection of a wheel (7), the wheel being provided with a boss (71), a plate section (72), and a rim (73) outward in the stated order in the radial direction, wherein the device is characterized in being provided with: a conductor (1) passing through a hole (711) in the boss (71); and a pair of auxiliary conductors (2) connected to the ends of the conductor (1) and extending in the radial direction of the wheel (7) outward from the boss (71) to the rim (73), the auxiliary conductors facing each other on both sides of the wheel (7). The pair of auxiliary conductors (2) and the conductor (1) are energized with alternating current.
