Abstract
An axial magnetic field vacuum interrupter includes a field producing structure associated with only one of two opposing electrode assemblies. The field producing structure is characterized in that when the instantaneous peak arc current is I.sub.m, measured in kiloamperes, and the electrode assemblies are in the open circuit position, the instantaneous component of the axial magnetic filed (AMF) B in the axial direction B.sub.a, measured in milliteslas, imposed on the majority of each electrode contact surface is given by the analytical expression. ##EQU1##
