一种基于趋肤效应的铁磁性导体磁化曲线测量方法及系统
摘要：
本发明涉及一种基于趋肤效应的铁磁性导体磁化曲线测量方法及系统，其系统包括信号源单元、电压检测单元和主控制单元。信号源单元连接在待测样品两端，为待测样品提供直流偏置电流和交流激励电流；电压检测单元检测待测样品上两个目标检测点之间的电压信号；主控制单元计算待测样品的电阻率和待测样品在对应偏置电流下的相对磁导率；还计算磁场强度和/或磁感应强度，并绘制待测样品的磁化曲线。本发明实现了铁磁性导体材料相对磁导率以及磁化曲线的无损检测，检测方便，灵敏度较高，测试稳定可靠。
摘要（英）：

The invention relates to a method and a system for measuring a magnetization curve of a ferromagnetic conductor based on a skin effect. The system comprises a signal source unit, a voltage detection unit and a main control unit, and is characterized in that the signal source unit is connected at two ends of a sample to be detected so as to provide DC bias current and AC excitation current for the sample to be detected; the voltage detection unit detects a voltage signal between two target detection points on the sample to be detected; the main control unit calculates the resistivity of the sample to be detected and the relative permeability of the sample to be detected under the corresponding bias current; and the main control unit is further used for calculating the magnetic field intensity and/or the magnetic induction intensity, and drawing a magnetization curve of the sample to be detected. The system provided by the invention realizes non-destructive detection for the relative permeability and the magnetization curve of the ferromagnetic conductor material, and is convenient in detection, high in sensitivity and stable and reliable in test.
