ABSTRACT:
Dispersion particles for a fluid having magnetic and electrorheological effects simultaneously, which comprise conductive ferromagnetic particles whose surfaces are coated with an electrically insulating layer and a fluid used the same. The present fluid has a larger torque induced upon application of both a magnetic field and an electric field than that in a fluid having only magnetic or electrorheological effects and higher response speed than that in a fluid having only magnetic. Furthermore, in the present fluid current difficultly passes.
