摘　　要：为了研究运动船舶磁性船体产生的感应电场,以库伦定律和毕奥-沙伐定律等电磁场基本理论为基础,对磁偶极子运动产生的感应电场进行了建模,通过实验证明了分析方法的正确性,解决了以往模型适用范围窄、准确性差的问题;并以磁偶极子感应电场模型为基础,得到了磁性船体的感应电场模型,利用实船的磁场数据进行了实例计算,得出船舶附近感应电场可达1m V/m,达到了可探测水平。In order to study the electric field induced by magnetic hull of moving ship, a mathematical model was proposed based on Coulomb and Biot - Savart laws. The correctness of this model was verified by the experimental measurements. The model has the characteristics of wide applicability and high computational precision, on the basis of which, the induced electric field distribution of moving ship was proposed. The simulation calculation was performed using the magnetic field data of a real ship. The result indicates that the induced electric field reaches 1 mV/ m around the ship, and it could be detectable.
