Abstract

A coupled magnetic/thermal model for studying heat and magnetic field diffusion in conducting materials subject to time-varying external fields has been developed, using the General Dynamics Thermal Analyzer code. Applications include energy storage devices, pulsed power transformers, and electromagnetic launchers, and the time scales of interest range from a magnetic field pulse of a microsecond to hundreds of seconds. The results of this model, showing the time and spatial variation of the magnetic field and temperature, are discussed for the projectile of an electromagnetic launcher
