During the motion process, the stagnation and back commutation occur and worsen the performances of circuit breaker. According to the real interruption process, a three-dimensional(3-D) model of arc motion under the effect of external magnetic field is built based on magnetohydrodynamic, which can predict the restriking phenomena. With air vents opened to 60%, the restriking phenomena occur under 3mT magnetic field; when the magnetic field is increased to 5mT, the restriking phenomena disappears.
