Abstract

Fast-burning mechanism describes the rapid penetration, with a sharp-shaped wave-front, of a strong magnetic field into a conductive metal whose electric resistance poses an abrupt rise at some critical temperature. With its wave-front sweeping over a solid metal, the fast-burning can melt or vaporize the metal very rapidly. This paper derives formulas for the existence conditions and wave-front velocity of a fast-burning.
