Abstract Research on regularity of indirect arc shapes change with variation of applied magnetic field is studied. Results show that indirect arc would be elongated or compressed in XOZ plane with variation of applied transverse magnetic field’s direction and intensity, while the indirect arc would be deflected with the application of longitude magnetic field in YOZ plane, and the deflection degree and direction will be also changed by the variation of longitude magnetic field’s intensity and direction. It is considered that change of arc shapes is caused by variation of arc forces. The influence of Ampere force on indirect arc deformation and deflection is analyzed in this paper.
