Experimental investigations of the stability behaviour of Nb Ti filamentary superconducting composites in a time-varying external magnetic field are reported. The magnetization due to the induced interfilamentary screening currents shows flux jumps. The influence of this sort of flux jump on dH/dt a
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.
In the concentric arrangement of a superconducting tube and a high-conductivity aluminium cylinder, the magnetic flux variation arising from flux jumps occurred only within the superconducting tube itself, whereas the magnetic flux in the normal metal was almost completely frozen during the flux jum
