摘要：
Equations that are used for the calculation and distributions of the electrical voltage U(t) output from a magnetic-field transducer as it scans a discrete magnetic medium with recorded residual magnetic fields, which were produced in it by acting individual magnetic-field pulses with opposite-polarity surges, are reported. The distributions were obtained via the Delphi programming language. The phenomenon of hysteretic interference (HI) of a magnetic field, which allows one to increase the accuracy of measurements, is used for the inspection of objects made from electrocoductive and magnetic materials.
