Effect of Applied Axial Magnetic Field on the Propagation of Cylindrical Shock Wave Generated by Exploding Wire

Abstract

The magnetohydrodynamic effect of an axial magnetic field on the cylindrical shock is studied theoretically on the basis of the blast wave theory. The result shows the reduced velocity of the shock front due to the applied magnetic field. Experiments were also carried out by use of exploding wires with or without magnetic field. The differences in shock arrival times of these two cases are compared and these are in satisfactory agreement with the above theoretical result.
