Abstract
A study has been made on the regularities determining the electrophysical properties of magnetic fluids based on decane, turbine oil and kerosene as functions of the electric field frequency, concentration of the dispersed phase and the temperature. The optimum frequencies of the electric field, concentration of the dispersed phase and temperatures, within which the electrophysical characteristics such as relative permittivity, specific electric resistance and dielectric loss tangent turn out to be the most informative for evaluation of the structure, compositions and properties of magnetic fluids, have been defined. Figs 5, Refs 3.
