摘要
利用Φ=∫SB.dS=∮lA.dl,逐一讨论单匝线圈自感、两线圈的互感和实际螺线管的自感系数的一般式,并借助于MATLAB快速便利地计算有限长多层直螺线管的自感系数.
By using φ=∫sB·dS=∮tA·dt,we discuss the self-inductance of single coil, mutual inductance of two coils and general form of practical solenoid. The results of inductance coefficient of finite and multi-layer straight solenoid can be rapidly evaluated by using the MATLAB.
