Magnetorheological fluid is an excellent versatile smart fluid. The applied magnetic field acts as an impulsive force on the fluid and shows changes in the rheological properties of the magnetorheological fluids. The viscosity of the fluid changes in response to magnetization due to the soft magnetic particles present in the fluid. The main problems identified in magnetorheological fluids are sedimentation and agglomeration of the particles. These drawbacks can be improved by optimizing the conventional properties and functionalization of the fluid elements. The decisive pinpoint of this research is to study the performance of magnetorheological fluid synthesized using three variant base fluids (fork oil, engine oil, and silicone oil) blended including a compatible additive and with iron particles dispersed in the fluid. The synthesized fluid’s rheological properties are investigated in both static and dynamic modes, and the observations were verified, with aim to optimize the efficiency and potential of the MR fluid. This study helps to choose an efficient sample for future damping applications in automobile industries.
