Background. The object of the study is measuring channels of magnetic induction and magnetic field strength, as part of a software and hardware complex for measuring the parameters of magnetic materials. The subject of the research is the development of functional and metrological analysis of measuring channels of parameters of magnetic materials. The aim of the work is to improve the metrological characteristics of measuring the parameters of magnetic materials. Materials and methods. The structure of a hardware and software complex for studying the parameters of magnetic materials is considered, in order to conduct a functional and metrological analysis of measuring channels of magnetic induction and magnetic field strength according to the methodology of G.P.Shlykov. Results. Structural and functional metrological models of measuring channels of magnetic induction and magnetic field strength have been developed. Conclusions. Analytical expressions and models of transformation of measuring channels are obtained. The models have limitations (losses on remagnetization, heating of the magnetic circuit), the elimination of which is the object of further research.
