Application of an external kilo-tesla-level magnetic field, which can be generated using high-intensity laser, to a target is a promising scheme to reduce spray angle of a laser-driven relativistic electron beam (REB) for enhancing the isochoric heating of a dense plasma with the laser-driven REB. Here we have developed a two-dimensional electro-magnetic dynamics (2D-EMD) simulation code to solve Maxwell equations with considerations of the inductive heating and temperature-dependence of electrical conductivity of a material for calculating temporally and spatially resolved two-dimensional profile of the externally applied magnetic field in a gold-cone-attached target...
