用费曼模型求截面为任意形状的无限长载流螺线管的磁场

Another solution for the magnetic field of an infinite solenoid of arbitrarily shaped cross-section with Feynman's model

利用载流线圈的费曼模型,根据截面为圆形的无限长载流螺线管的磁场分布和场叠加原理,求出截面为任意形状的无限长载流螺线管的磁场分布.

According to Feynman's model,the field superposition principle and the magnetic field of an infinite solenoid of circular crosssection,the magnetic field of an infinite solenoid of arbitrarily shaped crosssection is calculated.
