PURPOSE:To obtain the dispersing particles useful for the engine mounting, etc., composed of electric conductive ferromagnetic particles of which surfaces are covered by an electric insulating membrane, having a large torque induced by magnetic and electric fields with a quick response. CONSTITUTION:The dispersing particles composed of electric conductive ferromagnetic particles of which electric resistance is 10<5>OMEGAcm or less, and the surfaces of which are covered by an electric insulating membrane such as PE. Furthermore, a fluid having effects of both magnetic and electric viscosity is obtained by combining 1-90 (wt.) % of the particles with 99-10% of a electric insulating solvent such as alkylnaphthalenes, etc. |
