磁链导电线圈或电流回路所链环的磁通量。磁链嘂等于导电线圈匝数N与穿过该线圈各匝的平均磁通量φ的乘积，故又称磁通匝。Ψ＝Nφ在SI单位制中磁链单位是韦〔伯〕(Wb)。根据法拉第电磁感应定律,当磁通随时间变化时,在线圈中将产生感应电动势；该电动势ξ等于磁链嘂的时间变化率的负值ξ式中ξ与Ψ 的方向的选取符合右手螺旋关系。磁链与建立磁通的电流有关。电流I1在其所流经的线圈1中建立的磁链Ψ11称为线圈1的自感磁链Ψ11=N1φ11=L1I1式中φ11是 I1在线圈1中建立的磁通，N1是线圈1的匝数，L1是其自感。电流 I1在它附近另一线圈2中建立的磁链Ψ21称为线圈1对线圈2的互感磁链Ψ21＝N2φ21＝MI1式中φ21是I1在线圈2中建立的磁通，N2是线圈2的匝数，M是互感。在恒定磁场中,如果电流回路导线截面积较大时(见图),计算自感磁链可以有两种方法。一种是将磁场分为许多磁通管元dφ，对其中与全部电流I相链环者及与部分电流 I"相链环者区别对待；前者按整数匝数1匝考虑，而后者按分数匝数处理，该分数匝数取为I┡/I。只与部分电流相链环的磁通形成的磁链称为部分磁链，其值为而电流回路所链环的全部磁链为其中包括与全部电流相链环者 (I┡＝I)。另一种是将电流分为许多电流管元dI，求出电流管元所围面积的磁通φ，可得全部电流回路所链环的磁链为对于同一电流回路，上述两种方法所得结果一样。对于同轴电缆，内导体心中的磁通形成的磁链称内磁链Ψi；按上述两种方法均得出式中μ 是内导体心的磁导率,I是其中电流,l为电缆长度。而Ψi与内导体心的半径大小无关。
