Comparison of results of measuring the magnetic field of a crack by flux-gate meters with calculated data obtained within a model of constant magnetic charge density
Source abstract
Abstract
Results of measurements of the coordinate characteristic of the magnetic field and its maximum gradient for a surface crack rectangular in section are compared with analogous magnitudes calculated by a model of a constant magnetic charge density. The measurements were performed using fluxgate meters. The optimum agreement of data on the maximum gradient was obtained in finding the extreme of a function depending on the effective depth of the crack and height of the observation point. The obtained values of these parameters are weak functions of the crack size.
