Methods of mathematical modeling of complex systems are considered. To construct mathematical models of changes in the electrical capacity of microlayers of magnetic nanofluids, the universal statistical package IBM SPSS Statistics was reasonably adopted. To optimize the construction of models, a database of the electric capacity of a cell with a microlayer of magnetic nanofluid and a program for generating a calculated model of the electric capacity of a capacitor with a magnetic nanofluid for IBM SPSS Statistics and Microsoft Excel were developed.

Keywords: magnetic nanofluid, concentration, microlayer, polarization, electric field, mathematical model, regression model
