Abstract
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 ϵ ′, dielectric loss factor ϵ′′ϵ′′ and electrical conductivity σ are significantly changed when 0.02 ≤ f(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.
