Resumo

The calculated initial and hysteresis branches of the electric voltage U (H) in a pulsed magnetic field of strength H are presented, corresponding to the branches of magnetization in the operating magnetic field and the residual magnetization of an object made of ferromagnetic material and similar branches of the used magnetic carrier (MC). The impact on an object with MN was carried out by magnetic field pulses to obtain stationary states of magnetization of an object with an internal defect, the field of which is modeled by the field of a linear inductor, the construction of spatial distributions of hysteretic interference (HI) and the creation of programs for calculating HI, which made it possible to increase the accuracy of monitoring the properties of objects.
