Original Abstract Submitted
A magnetorheological fluid contains: a dispersion medium; and magnetic metal particles dispersed in the dispersion medium and having a coercive force of 398 A/m or less, which is equivalent to 5 Oe or less. A shear yield stress τmeasured at a shear rate of 0.01/s after a magnetic field of 0.5 T is continuously applied for 480 seconds and the magnetic field is removed is less than 2.0 times a shear yield stress τmeasured at a shear rate of 0.01/s before the magnetic field is applied.
