Magnetic hysteresis property of magneto-rheological fluid material under 2D fluxes

This paper systematically reports our recent study on the magnetic hysteresis property of magnetorheological (MR) fluid material under one dimension alternating and two dimension rotating magnetic field. The measurement was completed by a single sheet tester and a MR fluid sample container. The principle of measurement and the calibrating procedure of sensor coil are presented. The experiment results, such as H-B loop, H & B vector loci and lagging angle between H and B are analyzed and discussed. The results will be useful in the design of smart structure using MR material fluid.
