Abstract
The electrophysical properties of magnetic fluids based on decane and kerosene depending on the concentration of the dispersed phase and temperature under different electric field frequencies have been studied. Different structural states of magnetic fluids under relatively low and high concentrations of the dispersed phase have been revealed. The shift of phase transition temperature of the first order and that of dielectric permeability extremum to a region of lesser temperature with an increase of the dispersed phase concentration in a kerosene-based MF have been defined experimentally.
