摘要：
The effects of magnetic viscosity on measurement results of magnetic properties for permanent magnetic material are investigated, and the variation of magnetic viscosity coefficient with time and temperature was discussed at detail. It was turned out that the value of intrinsic coercivity increases with the magnetic field change rate. The relation curve between the magnetic viscosity coefficient and the applied magnetic field presents the parabola shape, and the peak was located in the magnetic field corresponding to intrinsic coercivity. The magnetic viscosity coefficient increases with temperature, enhanced magnetic viscosity effect was observed. © 2015, Chongqing Functional Materials Periodical Press Co. Ltd. All right reserved.
