摘要
为了测量多种形态磁性材料的磁滞回线,设计了磁滞回线测量仪.该仪器的磁感应强度探测器采用双线圈反相连接的方式,磁性材料可以放于任一探测线圈中,方便更换.测试表明,该套实验仪器具有良好的性能,输出图形清晰、分辨率高.
A hysteresis loop measurement instrument is designed. Its detector of magnetic induction density is composed of two coils with reverse connection. It can be used to measure various kinds of magnetic materials with different shape. Experimental results show that this device has clear output figure and high sensitivity.
