Abstract: A deterioration prediction device for a magnetic material is provided with: a magnetic sensor configured to detect a magnetic field affected by a magnetic body (W) as an inspection target and outputs a sensor signal; a deterioration score calculation means (51) configured to calculate a deterioration score indicating the degree of deterioration of the magnetic body based on the sensor signal; a deterioration score storage unit (41) configured to store the deterioration score; a deterioration prediction model storage unit configured to store a deterioration prediction model indicating a change in the degree of deterioration; a deterioration prediction model update means (52) configured to update the deterioration prediction model to acquire an updated deterioration prediction model; and a deterioration score prediction means (53) configured to estimate a future deterioration score.

Abstract: This magnetic body management system (100) includes: a first magnetic body inspection device (1) configured to acquire a detection signal (DS) before the magnetic body (MM) is installed at a location of use; a second magnetic body inspection device (2) configured to acquire a detection signal (DS) after the magnetic body (MM) has been installed at the location of use, the second magnetic body inspection device (2) having the same method as that of the first magnetic body inspection device (1); a server (3); a first transmission unit (4); and a second transmission unit (5). The server (3) is configured to estimate a deterioration state of the magnetic body (MM) based on at least the first magnetic body information (10) and the second magnetic body information (11).
