A magnetic viscoelastic material, which consists of viscoelastic silicone gel and dispersed carbonyl iron powder of approximately 7 μm diameter (magnetic micro-particles), has synthesized in order to create highly deformable body under action of magnetic field. Due to high magnetic body force derived from high magnetization character of grain, extremely large deformation of viscoelastic body is expected under strong magnetic field gradient, while keeping solid character of the compound. In the present study, some of mechanical characteristics of the magnetic viscoelastic material are introduced. Opening and closing operation (the aperture control) of a plug placed in a straight tube id performed, and the results of basic experiment are displayed and discussed in connection with applied magnetic field. The results of flow experiment indicate that the material has very fast response character in controlling flow rate.
