MAGNETIC FUNCTIONAL FLUID, DAMPER AND CLUTCH USING MAGNETIC FUNCTIONAL FLUID |
| 摘要 |
Magnetic functional fluid includes dispersion medium; and dispersed particles which are dispersed in the dispersion medium, wherein the dispersed particles includes: first ferromagnetic particles having an average particle diameter of 0.5 μm to 50 μm; and second ferromagnetic particles each having a needle-like shape, each having a smaller particle size than the first ferromagnetic particles, and each having a length ratio of a long axis to a short axis of 2 or more. |
