讨论了磁粘滞行为对永磁材料磁参数测量结果的影响，并具体分析了不同磁场强度和温度下磁粘滞系数的变化情况，结果表明，内禀矫顽力数值随磁场变化率增大而增加。磁粘滞系数与作用磁场的关系曲线呈抛物线形，且峰值出现在内禀矫顽力数值附近。随着温度的升高，磁粘滞系数的增大，样品的磁粘滞效应增强，磁场变化速率对内禀矫顽力测量结果影响增大。

The effects of magnetic viscosity on measurement results of magnetic properties for permanent mag-netic 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 pres-ents 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.
