柱坐标下毕奥-萨伐尔定律及其应用
摘要
Abstract
Beginning with the differential form of the Biot-Savart law,the expression of the Biot-Savart law in cylindrical coordinates is derived in detail,and this form is used to calculate the magnetic field distribution in space generated by axisymmetric current-carrying wires such as finite length straight wires,current-carrying circular coils,and infinitely long current-carrying cylinders.The results demonstrate that the cylindrical coordinate representation of the Biot-Savart law offers greater convenience for determining magnetic fields produced by axially symmetric current conductors.Notably,in calculating the magnetic field generated by a current-carrying circular coil at any point in space,the final result can be obtained by only calculating the integral of the radial and angular components of the magnetic field.关键词
