Abstract
Time dependences are given for an electric voltage U(t) that is recorded across an inductive magnetic head when scanning a discontinuous magnetic carrier that has been subjected to pulsed magnetic fields of a linear inductor. The value of U(t) at each point of the carrier is determined by the amplitude of each pulse, the pulse direction, and the sequence of exposures. If a current-conducting object is present, this value also depends on the field pulse rise time. The phenomenon of hysteretic interference of a pulsed magnetic field (HI) is used. Digital images of pulsed magnetic fields, as well as computer-assisted methods for measuring these fields, finding their distributions, and processing observation results are presented.
