摘要: Superconducting wire carrying transport alternating current with amplitude around its critical exhibits two main loss mechanisms: besides the irreversible pinning of magnetic flux leading to losses that have prevailed at low currents, resistive appears due nonzero resistivity in overcritical regime. We tested hypothesis total is an algebraic sum both these components. Resistive were derived from measured DC current-voltage curve, and established by a contactless method. found that, case multifilamentary Bi-2223/Ag tape, terms was fair agreement traditional way.
