INFLUENCE OF THE COMPOSITION AND TEMPERATURE OF CONCENTRATED MAGNETIC FLUIDS ON THEIR ELECTROPHYSICAL PROPERTIES FOR DIFFERENT FREQUENCIES OF THE ELECTRIC FIELD
V. I. Zubko, A. I. Lesnikovich, and D. V. Zubko UDC 537.226.2:537 A study has been made of the regularities determining the electrophysical properties of magnetic fluids based on decane, turbine oil, water, and kerosene as functions of the frequency of the electric field, the 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 the relative permittivity, the specific electrical resistance, and the dielectric loss tangent, turn out to be the most informative for evaluation of the structure, compositions, and properties of magnetic fluids have been determined.
