• Mean power losses produced in a cylindrical specimen, when an external magnetic field along the cylindrical axis is increased with a constant rate, are calculated under an assumption that the temperature inside the specimen is uniform. With the aid of this result, a simplified heat equation to describe the variation of the temperature of the specimen with time is derived. Then, calculations are carried out for several qualities vitally concerned with flux jumps, e.q., the relation between the flux jump field and the sweeping rate, the minimum field for the flux jump, and the jump intervals. In addition, an analysis of temperature fluctuations is worked out under the condition of small heat leakage, and the results are compared qualitatively with the experimental data on Nb^Ti rods.
