摘要：

Magnetic stability of AC superconducting wires was investigated experimentally. In a long superconducting wire, self-field cannot diffuse sufficiently, and it has been thought that flux jumping occurs when the thickness of the saturated region is larger than some threshold value in multifllamentary superconductors. In this paper, we measured a current sweep rate dependence of quench current of the AC superconducting wire. The experimental results indicated that AC superconducting wires were magnetically stable and could carry the critical current at the sweep rate that was 100 times higher than a threshold value which was estimated from one-dimensional diffusion equation.
