ResumoThe stability of magnets under weak random thermal disturbances is considered. These disturbances correspond to sudden energy releases due to construction noise (epoxy cracks, fractures, micro- deformat ions ect.). We apply the theory of stochastic processes to assess the permissible critical level noise. Criteria of stability for Gaussian and Poissonian thermal disturbances are obtained, and the permissible level of temperature fluctuations at a given current is determined. The stability criteria depend on the effective spatial dimensionality of a problem and the statistics (Gaussian or Poissonian) of the disturbances. The application of theory to safety and protection problems is discussed.
