交流磁滞回线的单片测量法

The Single Sheet Measurement of AC Hysteresis Loop

分析了交流磁滞回线两种传统的测量方法(爱波斯坦方圈法和环形样品法)的缺点,阐述了通过B线圈和H线圈来检测磁感应电压,从而得到磁感应强度和磁场强度的单片测量方法与磁通波形的控制方法,并实现了计算机自动测量。此方法较爱波斯坦方圈法和环行样品法更能方便准确地获取交流磁滞董回线。

Based on analysis of the drawback of two traditional measuring methods for AC hysteresis loop, a method of single sheet measurement is proposed which employs B coil and H coil to detect the induced voltages to get magnetic induction and field strength. Automatic computer-controlled measurement can be achieved. This method is more convenient than the two traditional methods to obtain dynamic AC hysteresis loop.
