摘要: 采用级数展开的方法,得到了一般情况下两共轴圆线圈间互感系数的严格无穷级数表达式,所得结果在除两线圈重合之外的所有情况下均是收敛的.并且在计算过程中利用磁矢势而非磁感应强度求出磁通量,使得该方法较为简便.

Abstract: The series expansion method is used to get the exact infinite series expression of the mutual inductance between two coaxial circular coils in general situation.The infinite series is convergent in all cases except for the two coils coincide with each other.Moreover,vector potential,instead of magnetic induction,is used to calculate the magnetic flux,which makes the method more convenient.

Key words: mutual inductance, coaxial coil, circular current loop, magnetic vector potential, infinite series
