An experimental study of the effect of nonuniform axisymmetric magnetic field on the breaking of the current of a vacuum-arc discharge

An experimental investigation is made of the effect of breaking of current in a vacuum-arc discharge as a result of superposition of a pulsed axisymmetric magnetic field with longitudinal and transverse components. A study is made of the dependences of the probability of breaking of current on the current magnitude, the pulse amplitude of the magnetic field, and the value of emf of the electric circuit in the current range of $100$ to $600$ A. The main factors affecting the probability of breaking of current are analyzed.
