The results of investigation of the distribution of electrical and magnetic properties over the cross-section are presented for Cu98Be2/Fe20Co6Ni74 composite wire of the \highly conductive core-magnetically soft coating" type, obtained by electrolytic deposition of the FeCoNi layer. Studies performed by the magneto-impedance tomography (MIT) made it possible to determine the speci¯c electrical conductivity of the materials of the core and coating. It was established that the electrodeposited coating had a magnetic structure that was inhomogeneous over the thickness. © World Scienti¯c Publishing Company.
