Iron carbonyl is decomposed, at the temperature of 473 K ± 10%, into a liquid matrix formed of silicone oil and stearic acid. For 3.703% and 1.886% stearic acid, magnetorheological suspensions (MRSs) are obtained. The iron particles in MRSs have the mean diameter of 0.356 μm. Magnetoresistors are achieved from MRSs with the dimensions of diameter and length equal to 5 mm. In longitudinal magnetic field, the resistance of the magnetoresistors is measured. Assimilating the resistance of the magnetoresistors with that of a linear resistor, the conductivity σ of MRS is determined. The duration tc of onset of σ is determined. It is observed that tc is considerably influenced by the intensity of the magnetic field applied and by the composition of MRSs. Experimental data are discussed, too.
