摘要
采用RL交流电桥来测量磁性材料的居里温度,通过分析升温和降温两种过程曲线,研究低频和高频工作状态对测量磁性材料居里温度的影响。结果表明:工作频率的高低对测量磁性材料居里温度的影响不大,但在高频条件下测得的居里温度更精确,这符合铁氧体磁性材料具有适于更高频率下工作的特性。
By using RL AC Bridge,Curie temperature of magnetic material is measured.Through analysis of two process curves of heating and cooling,the influence of Low-frequency and High-frequency on measuring Curie temperature of magnetic material is studied.The experiment results show that measuring Curie temperature of the magnetic material is not too much affected by high or low working frequency,but Curie temperature is accurate at high frequency and this is in accordance with the fact that Ferrite magnetic materials are fit for working at high frequency.
