: Magnetorheological (MR) fluids belong to a class of smart fluids that exhibit dramatic but reversible change in the fluid characteristics in response to applied magnetic field. It consists of tiny ferromagnetic micro-particles suspended in carrier fluid. The MR fluid has the ability to change from a fluid state to a semi-solid or plastic state instantaneously upon the application of a magnetic field. The fluid exhibits visco-elastic behavior that is characterized by the field dependent yield stress in this semi-solid state. This highly desired characteristic of field dependent yield stress and their quick response time to the applied magnetic field has drawn attention of thousands to harness such technology in many applications. MR fluid technology has shown its presence in engineering and medical applications, though new applications continue to evolve. These emerging applications, and many current applications, subject the fluid to extreme flow conditions. Specifically, these flow environments or conditions include high shear and high velocity flow. The challenge in such devices becomes the lack of information regarding the behavior of MR fluid under these adverse operating conditions. This paper will review the fundamental behavior of MR fluid and present some of the existing and emerging MR fluid devices and hence provide relevant information to the budding researchers in MR fluid technology.
