The purpose of this paper is to establish the theoretical prediction that the steady torque characteristics of a rotating disk in ERF can be quantitatively and qualitatively explained. At the first step on the basis of this purpose, the ER effects of electric field and shear rate were investigated by comparison of experimental results of the flow curves between the rotating concentric cylinder type device and the rotating disk one. We clarified experimentally the difference of these flow curves influenced by the electrode gaps.
