Abstract
Experimental studies of the kinetics of flux jumps in type II superconducting disks have shown that flux penetration into the specimen can be described by an exponential function of time. We present a phenomenological theory which uses the concepts of flux pinning and flux flow viscosity to derive a function of the same form as that found experimentally. The function can be used to evaluate the average pinning force and the viscosity from experimental data on flux jumps.
