摘要：
A model of vacuum arc cathode spot motion in a magnetic field which obliquely intercepts the cathode surface was developed. The model takes in account an electrical force generated by spot motion across the normal component of the magnetic field, which accelerates plasma in the direction of the opening of the acute angle. A relation between the drift angle (between the retrograde direction and the cathode spot motion) and the acute angle formed by the intersection of the magnetic field lines with the cathode surface, was developed. The dependencies of the drift angle on the acute angle and magnetic field strength measured in Robson's experiment were analyzed.
