Abstract
Diffusion of a magnetic field into a conductor featuring a metal-insulator phase transition caused by Joule heating is theoretically studied. Development of a thermomagnetic instability at the metal-insulator interphase boundary moving in a fast wave regime is described in the linear stage depending on the wavenumber. Effect of the interphase boundary instability on the operation of a fast-speed electric current breaker based on a (V1−X CrX)2O3 solid solution is assessed.
