Summary

GAIN IN JOULE LOSSES WITH TEMPERATURE INCREASE CAUSES AN EQUILIBRIUM TO EXIST BETWEEN HEATING AND COOLING IN AN ELECTRICAL WINDING ONLY AT CURRENTS LESS THAN SOME CRITICAL VALUE. THIS EFFECT IS ESSENTIALLY IMPORTANT FOR HYPERCONDUCTING WINDINGS, IE WINDINGS MADE OF ULTRAPURE CONDUCTORS WHOSE RESISTANCE AT LIQUID NITROGEN, HYDROGEN AND HELIUM TEMPERATURES IS TWO OR THREE ORDERS OF MAGNITUDE LESS THAN AT ROOM TEMPERATURE. THE EFFECT OF BOILING CRYOGEN CRISIS ON THE CRITICAL CURRENTS IS CONSIDERED.
