Abstract
Measuring results of vacuum arc voltage under the influence of a transverse magnetic field are presented in the paper. The arc current half-wave had amplitudes from 100 to 600 A and frequency of about 30 Hz. The field was oscillatory (450 and 900 Hz, amplitudes from 15 to 200 mT) as well as proportional to the current values. Arc voltage in relation to field density, arc current and contact distance were observed and discussed. Arc photographs (2000 frames/s) show constriction of the arc and its motion according to Lorentz force acting on ions
