Abstract
An electrorheological magnetic fluid including an electrically insulating liquid and fine particles dispersed therein is described, wherein the fine particles include a fine magnetic particle as a core, wherein the fine magnetic particle has a surface which is covered by an electroconductive substance, and the fine magnetic particle with its surface covered by the electroconductive substance is completely coated with a surfactant. A process for producing the electrorheological magnetic fluid is also described.
