The MR fluid device (20) includes a housing (22) including a hollow (30), a moving element (26) contained within the hollow (30), the housing (26) and moving element (26) cooperating to form a working section (36) and a chamber (32)

A magnetorheological (MR) device (20) including settling stability. The MR fluid device (20) includes a housing (22) including a hollow (30), a moving element (26) contained within the hollow (30), the housing (26) and moving element (26) cooperating to form a working section (36) and a chamber (32) within the hollow (30), a MR fluid (38) contained within the working section (36) and the chamber (32), a coil (40) or the like for generating a magnetic field to act upon the MR fluid (38) contained within the working section (36) to cause a rheology change therein, and a magnet (25) or electromagnet (31) generating a low-level magnetic field to act upon a substantial portion of the MR fluid (38) contained in the chamber (32) to minimize settling of the particles in the MR fluid. Linear and rotary acting embodiments are included.
