Magneto-induction experiments have been devised to measure the microstructure response of quiescent magnetorheological (MR) fluids to an applied magnetic field. Unlike many previous techniques this measurement technique is well suited for MR fluids of high iron loading. Two distinct time scales of microstructure formation have been observed within the range of 10-3to 10-1seconds. These two time constants are thought to be associated with floe or chain formation and chain growth and migration. The dependency of the time response upon volume fraction, carrier viscosity and applied field is in partial agreement with contemporary theories and models of particle aggregation.
