Abstract
A magnetorheological fluid composition comprising a carrier fluid; and a plurality of high aspect ratio magnetizable particles, wherein the aspect ratio of the high aspect ratio magnetizable particles is greater than 1.5. Optionally, the high aspect ratio magnetizable particles can have interlocking structures comprising male component and a female component. Still further, a magnetorheological fluid composition can comprise low aspect ratio magnetizable particles having the interlocking structures, wherein the aspect ratio of the low aspect ratio magnetizable particles is 1 to 1.5.
