Dependences of the viscosities of magnetic fluids based on kerosene and water on the concentration, temperature, and the strength of an external magnetic field are investigated using an analytical expression for the shear viscosity coefficient, obtained via nonequilibrium statistical theory. Calculations based on the expression for the shear viscosity coefficient show that viscosity grows nonlinearly along with concentration and falls as the temperature rises, in agreement with experiments. Allowing for dipole–dipole interaction between magnetic particles and their interaction with an external magnetic field, a magnetoviscous effect is revealed in the studied magnetic fluids, and qualitative agreement is reached between calculations and experimental data.
