Abstract
Magnetorheological (MR) fluid is a type of smart material that exhibits fast, tuneable, and reversible changes in its rheological properties under the influence of a magnetic field. It is a suspension of small iron particles that can be arranged into chains when exposed to a magnetic field, resulting in a dramatic increase in the fluid's viscosity. A recent study investigated the properties of the three main components of MR fluid, namely soft magnetic particles, carrier fluid, and stabilizing agent, at high-temperature and developed a novel MR fluid that is resistant to sedimentation and temperature. The new fluid exhibited excellent sedimentation stability, higher shear yield stress, and less sensitivity to high-temperature environments, expanding its potential applications in MR devices.
Keywords: - magnetorheological fluid, magnetic field, viscosity, stabilizing agent, sedimentation
