The theoretical approach is carried out with the combined thermal and magnetic equations which are based on the critical state model for non-ideal type-II superconductors and include controllable physical parameters. Also, the behaviour of flux jumps is studied on Nb-Ti-Zr ternary alloy wires in the

THE critical current lc of a type II superconductor, taken from a short sample measurement, is not a well defined function of the magnetic field H. Sometimes le(H) depends on the way current and field are raised. This means there is an ambiguity of Ie which can be explained by circulating currents
The appropriate magnetic and thermal diffusion equations for magnetization of a "hard" type II superconductor have been solved numerically using a digital computer, and show the initiation of flux jumps at applied field strengths in agreement with experimentally observed magnitudes.
