Magnetic field diffusion in a conducting half-space in the case of a linear rise in current intensity
Abstract
The effect of the magnetic Prandtl number (and therefore heat conductivity) on the heating of a conducting half-space carrying a current whose intensity increases linearly is investigated analytically. The results are compared with the case of conductor heating in the case of electromagnetic field diffusion without allowance for heat conduction. The half-space may represent a model of a conductor surface if the characteristic time of the process is such that the magnetic field does not penetrate far enough to be affected by irregularities of the cross-sectional shape of the conductor.
