Production of magnetorheological suspensions based on silicon oil, stearic acid and iron nanocarbonil (CI) microparticles is achieved by the method of mechanical mixing. Magnetorheological suspensions with concentrations (in massic percentages) of 20%, 60% and 80% are produced, used in manufacturing magnetoresistors. It is shown in the paper that the magnetoresistors resistance is considerably influenced by the magnetic field intensity. By resistance measurements, characteristic magnitudes, which participate in the electric conductivity phenomenon in magnetorheological suspensions in magnetic field, are determined.
