本文研究了测量硬铁磁材料磁粘滞系数的实验方法，即在恒定磁场和温度下记录材料磁饱和后的磁化强度。它调查的方法（饱和场，场变化率和场振荡之前，其稳定）的初始条件，并通过记录过程中的字段和温度的微小变化的实验结果是如何受到影响。基于得出的结论并使用更复杂的测量拟合函数，提高了实验结果的准确性和重复性。
This work is an investigation of the experimental method used for measuring the magnetic viscosity in a hard ferromagnetic material, i.e. the recording of the magnetization under constant applied field and temperature, after the material has been magnetically saturated. It investigates how the experimental results are affected by the initial conditions of the method (saturation field, field change rate and field oscillation prior to its stabilization), and by minor variations of field and temperature during the recording. Based on the arising conclusions and the use of a more complex fitting function of measurements, the accuracy and repeatability of experimental results is improved.
