Abstract

The magnetic flux density in the magnetizing coil during the hysteresis measurement was calculated. The influence of a slot, machined in a ferromagnetic plate was simulated. The size of the magnetizing yoke was changed and the influence of this modification was studied on the detectable flux density. The size of the slot and the thickness of the air gap, which appears between the magnetizing yoke and plate's surface, was also taken into account. It was found that by this simulation the experimental conditions could be successfully modelled. A sensitivity analysis of the studied nondestructive testing setup was also performed and the impact of different experimental parameters was analyzed. The results of simulation can be used successfully for determining the optimal parameters of the actual measurement arrangement if method Magnetic Adaptive Testing measuring technique (which is based on systematic measurement and evaluation of minor magnetic hysteresis loops) is applied.
