<P>PROBLEM TO BE SOLVED: To provide a magnetic viscous fluid that has high density magnetic particles, long-lasting excellent magnetic viscous properties, can maintain favorable dispersion stability, and is free from precipitation of magnetic particles. <P>SOLUTION: The magnetic viscous fluid contains metal-oxide particles having a specific average particle diameter and magnetic particles having a specific average particle diameter which are dispersed in a dispersion medium at a specific compounding ratio, and contains at least 0.5 to 5 weight percent of oxidized polyethylene as a viscosity adjustor against magnetic particles. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
