The paper presents measurement and comparison of the dynamic viscosity of commercially available magnetorheological fluids and their temperature dependency of the dynamic viscosity. The appropriate choose of the MR fluid has positively effect to efficiency of the magnetorhelogical damper. The lower value of the dynamic viscosity (magnetic field independent) increases the dynamic force range. Eight samples of MR fluids from three manufactures were measured. MR fluids were tested on the Haake Rotovisco 1 in the temperature range -5 °C to 100 °C. The lowest dynamic viscosity with the similar solid content by weight is exhibited by MR fluids manufactured by Lord company.
