摘　　要：根据断丝漏磁场的特征,对钢丝漏磁场的产生进行了分析;提出基于棱分布的断丝漏磁场解释模型;对钢丝直径和提离值对漏磁场的影响进行了分析;与简化的点磁荷模型进行了比较研究,获得了钢丝漏磁场的点磁荷模型简化条件。According to the characteristics of the magnetic leakage field of broken wires, magnetic field leakage is analyzed in this paper, the interpretation model of the magnetic field leakage is proposed based on the edge distribution of broken wires. The influence of wire diameter and the lift-off value on the leakage of magnetic field is analyzed. Comparing with a simplified model of magnetic charges, the simplified conditions of the point magnetic charge model is obtained.
