Abstract in different language:	In the paper we introduce a general formula describing the time- space distribution of the magnetic pressure in a conducting tubular workpiece placed in external magnetic field having the character of a damped sinusoid. For the case of a circular workpiece we determine the transient electromagnetic field using the solution of Bessel equation in cylindrical co-ordinates, and also applying the integral Lapalce transform. Next we determine the time-space distributions and instantaneous magnetic pressure inside the workpiece. The solution we obtained is illustrated by relevant graphs for different values of the parameter considering the external dimension and the depth of diffusion of the electromagnetic field.
