Magneto-rheological (MR) suspensions are actively used in damping devices. As a rule suspensions are magnetic particles in a nonmagnetic environment. The control and field influence are carried out only at the expense of the MR effect. In this article the dissipative environment on a magnetic fluid basis is presented. This gives opportunity to use additional controlling mechanism by this environment at the expense (using) ponderomontive force. It will allow to create the local volume of magnetic environment in the given local place. The attention is given to account of the dissipation force at theoretical investigation of the plate oscillation and corresponding calculation of the damping decrement.
