👉 A magnetic fluid, also known as magnetorheological (MR) fluid, is a unique material that combines the properties of a liquid and a solid. It consists of micron-sized magnetic particles suspended in a carrier fluid, typically oil. When an external magnetic field is applied, these particles align and form chains or clusters, dramatically increasing the fluid's viscosity and transforming it from a liquid to a semi-solid state. This reversible change in viscosity allows MR fluids to be used in various applications, such as dampers, clutches, and shock absorbers, where they can quickly adapt to changing conditions by adjusting their stiffness in response to magnetic inputs.
