Magnetorheological devices, including damping devices, rotary devices, and haptic systems constructed with said devices are disclosed. The devices contain dry magnetically-responsive particles, or MR fluids containing the magnetically responsive particles. The magnetically soft particles characterized by a single process yield population of atomized particles having a cumulative 10 %, 50 % and 90 % by volume, fraction within specified size, i.e., D10 of from 2 up to and including a D10 of 5 µm, a D50 8 µm up to and including a D50 of 15 µm, a D90 of 25 µm up to and including a D90 of 40 µm, and characterized by a least squares regression of log normal particles size against cumulative volume % fraction of greater than or equal to 0.77. |
