Based on models of the electromagnetic field and elastic-plastic deformation in a continuous medium, two modes of destruction during the cyclic process of generating pulses of a strong magnetic field are investigated: accumulation of residual deformation and low-cycle fatigue in the surface layer of the conductor. It is shown that both mechanisms of destruction act simultaneously. At the same time, the first of them limits the resource of the inductor at the level of hundreds of pulses. The destruction by the mechanism of low-cycle fatigue becomes the main factor limiting the inductor's life in the case of oscillatory magnetic field pulses with relatively small attenuation at induction amplitudes below 20 T. The resource of the product in this case is estimated within 103-104 pulses. © 2023 The Authors. Published by ELSEVIER B.V.
