A device for predicting deterioration of a magnetic material and a method for predicting deterioration of a magnetic material

摘要

A magnetic sensor 10 that detects the magnetic field affected by the magnetic body W to be inspected and outputs a sensor signal, and a degradation score calculating means 51 that calculates a degradation score indicating the degree of degradation of the magnetic body based on the sensor signal and a deterioration score storage unit 41 for storing a deterioration score, a deterioration prediction model storage unit 42 for storing a deterioration prediction model indicating a change in the degree of deterioration, and a deterioration prediction model after updating by updating the deterioration predictive model A deterioration prediction device for a magnetic body, comprising: deterioration prediction model updating means (52) to acquire; and deterioration score prediction means (53) for estimating a future deterioration score.
