Abstract
The retrograde motion of the cathodic arc attachment point in a transverse magnetic field is examined and is attributed to the asymmetrical confinement of the cathode spot plasma which results from the asymmetrical combination of the self and applied magnetic fields. This confinement of the cathodic vapor on the retrograde side of the microspot enhances the electron emission on that side and thus favors the observed retrograde motion of the arc attachment point. The model is shown to be consistent with a number of reported features of the retrograde motion and the cathode spot.Keywords
