A magnetorheological (MR) fluid is a fluid that has good magnetic properties. MR fluid responds to the magnetic field and changes its properties when a magnetic field is presented. The areas of application for MR fluids are MR dampers, brakes, clutches and MR valves. The working principles of the MR fluid flow rheological behavior is based on an infinite chain of particles aligned along with the direction of the magnetic field (H). That is the case when there is a gap between any two plates where a magnetic field is applied. This article investigates the modeling behavior of magnetorheological fluid. The model working principle is based on the dipole interaction of particles within a presumed structure. The bipolar model is augmented with a mechanism. The mechanism helps magnetic flux density to distribute in the iron particle network. Modeling of MR fluid is dependent on many models; e.g., the Bingham model, the Herschel-Bulkley model, the Biviscous model, Hysteretic Biviscous models and others. The Bingham Plastic model is considered the best model to describe the relation between the magnetic field and shear stress of MR fluid. The modeling of MR fluid is dependent on the type of mode and application. The mathematical model of flow in MR valve models and modeling of brakes are presented. These models can be used in application design of MR fluid devices.
