Abstract
A magnetorheological fluid that includes a carrier component and a magnetizable particle component wherein the magnetizable particle component has a fractional packing density of at least 0.50 prior to formulation into the magnetorheological fluid. Use of this magnetorheological fluid can increase the force output of a magnetorheological device without increasing the viscosity of the fluid because the particle volume concentration in a working gap of the device increases when a magnetic field is applied.
