Summary

THE BEHAVIOUR OF A SUPERCONDUCTING COMPOSITE SUBJECTED TO A TRANSVERSE TIME-VARYING MAGNETIC FIELD HAS BEEN SIMULATED WITH AN ELECTRICAL NETWORK. THE PROBLEM OF THE CURRENT DISTRIBUTION INSIDE THE COMPOSITE HAS BEEN SOLVED WITH A COMPUTER CODE. THE RESULTS CLEARLY SHOW THE EXISTENCE OF DIFFERENT ZONES (SATURATED, INTERMEDIATE, AND SATURATION-FREE ZONES) AS WELL AS THEIR EVOLUTIONS WHEN THE FIELD VARIATION RATE B INCREASES. THE LOSS POWER HAS BEEN ALSO CALCULATED. IT IS FOUND THAT THE PENETRATION OF THE SATURATED ZONES IN THE MIDDLE PLANE OF THE COMPOSITE IS RELATIVELY EASY, AND THAT THE CENTRE IS REACHED FOR A FINITE VALUE OF B. HOWEVER, THE TOTAL SATURATION OF THE WHOLE COMPOSITE IS ACHIEVED ASYMPTOTICALLY ONLY WHEN B BECOMES INFINITE.
