| description | PROBLEM TO BE SOLVED: To provide a magnetic viscous fluid which is not only hard to cause magnetic particle settling, secondary agglomeration and the like, but also small in shear stress even in a region with a high shear rate.SOLUTION: A magnetic viscous fluid comprises: a magnetic particle mixture; and a dispersant with the magnetic particle mixture dispersed therein. The magnetic particle mixture includes first magnetic particles and second magnetic particles. The first magnetic particles each have a first magnetic particle main body, and a first surface-modification layer provided on the surface of the first magnetic particle main body. The second magnetic particles each have a second magnetic particle main body, and a second surface-modification layer provided on the surface of the second magnetic particle main body. The first magnetic particles have an average particle diameter of 1-50 μm. The second magnetic particles have an average particle diameter of 50-200 nm, and account for 0.5-2 wt% of the magnetic particle mixture. |
