Basic Properties of Magnetorheological Fluids for Optical Finishing

Abstract

Magnetorheological (MR) fluids are multicomponent systems consisting of a non-colloidal magnetic-dispersed phase in a carrier liquid, which undergo rapid, sharp and reversible changes of their internal structure in an external magnetic field. As a consequence, their rheological properties, such as viscosity, plasticity and elasticity are controllably changed (for example, see Figure 1).
