Magnetic instabilities or flux jumps in multifilamentary superconducting composite conductors, exposed to a time-varying magnetic field perpendicular to the superconducting filaments, are studied. In particular, expressions for the stability limit field are determined for cases when the magnetic dif

β¦ Synopsis
The stability limit field, Bfj, is determined for single core superconductors, when an external magnetic field changing linearly with time is applied perpendicularly to the axis of a cylindrical sample. Cases are considered when the magnetic diffusivity is greater than the thermal diffusivity and vice versa. The results are applied to a NbTi sample.

The influence of dc transport currents on alternating-field hysteresis loss was investigated for a single core superconducting wire. The configuration of the sample coil simulates a tight solenoidal winding of superconducting magnets, and the field is a small transverse alternating field applied on
At relatively high ampfitudes and variation rates of a transverse external field, the saturated zone may occupy a considerable part or the entire space of the composite. Differential equations have been derived which enable one to calculate the time dependence of the magnetic moment of screening cur
The influence of oscillating magnetic fields on the dc transport current in a single core superconducting wire has been studied by observing the terminal voltage of the wire. The voltage versus oscillating field characteristics can be explained quantitatively by a theoretical analysis based on the c
