摘要：

A description of the method of magnetoimpedance tomography is presented. This method is based on the analysis of the frequency dependences of the impedance obtained in magnetic fields of various strengths. It allows one to determine the distribution of electrical and magnetic properties over the cross-section of the conductor, as well as their dependence on the magnetic field. The article proposes a specific approach to the implementation of the magnetoimpedance tomography method based on computer modeling by the finite element method. The results of this method are presented for composite Cu98Be2/Fe20Co6Ni74 wires of the "highly conductive core-magnetically soft coating" type and amorphous rapidly quenched Co66Fe4Nb2.5Si12.5B15 wires.
