POWER EMITTED INSIDE A CONDUCTING CYLINDER PLACED IN LONGITUDINAL UNIFORM TRANSIENT MAGNETIC FIELD

摘要

The paper deals with determination of the transient electromagnetic field in a conducting cylinder placed in external uniform magnetic field, Computations are realized by means of solution of the Bessel equation in cylindrical co-ordinates using the Laplace integral transformation. Then, the Poynting theorem is used to determine the superficial density of the instantaneous power flux diffused into the cylindrical charge and instantaneous volume density of the power converted into heat, That allows determining the instantaneous power converted into heat, and, therefore, the energy of the heat emitted into the charge, These results can be used to describe the transient temperature field inside the heated charge
