Abstract The aim of this paper is to investigate the behaviour of the total energy of a magnetoelastic conductor occupying a semi-infinite prismatic cylinder in dynamical conditions. Precisely, we deduce some estimates for the energyW(x 3,t) of the portion of the medium at distance greater thanx 3 from the base in terms of the data. First of all, we prove that the total energyW(0,t) is finite for allt 〉 0 providedW(0, 0) is finite. Then, using the first Korn inequality, we obtain that the estimate forW(x 3,t) depends only on the initial data ift〈x 3/V (V=computable positive material constant); ift〉x 3/V then the bound forW(x 3,t) depends on all the data of the problem.
