We have obtained hybrid magnetorheological suspensions (MRS-hybrid) consisting of magnetorheological suspension (MRS), magnetorheological elastomer (MRE) and polyurethane sponge foam (PSF). We measure the capacitance and resistance of a plane capacitor based on MRS-hybrid, as a function of frequency f of an electric field superimposed with a magnetic field of intensity H. The relative dielectric permittivity epsilon', dielectric loss factor 6 and electrical conductivity a are significantly changed when 0.02 <= J(kHz) <= 200 at H = 0, 100, 200 and 400 kA/m. The static and optical dielectric constants are greatly influenced by the magnetic field intensity. We present and discuss the results using the model of dipolar approximation.
