本文考虑了与动作电位沿圆柱形纤维传播相关的动作电流产生的磁场。磁场的等效电流源恰好是膜两侧的轴向电流密度差。 Fibre bundles are considered by superposition.总磁场变化为 0(1/R3)，因此它是四极的。等效源与膜和周围介质之间的电导率不连续性的相关性比与离子（初级）电流的直接相关性更强。
This paper considers the magnetic field arising from action currents associated with the propagation of an action potential along a cylindrical fibre. The equivalent current sources of the magnetic field are precisely the difference in axial current density on each side of the membrane. Fibre bundles are considered by superposition. The total magnetic field varies as 0(1/R3) hence it is quadrupolar. The equivalent source is more strongly related to the discontinuity in conductivity between the membrane andsurrounding media than directly to the ionic (primary) currents.
