Magnetic Field Induced by Screening Current in Short and Straight Coated Conductors

This paper presents experimental results and analyses of spatial and temporal variations of a screening-current-induced magnetic fields (SCFs) and remnant trapped fields for a short coated conductor (CC) and CCs superimposed each other. The variations are evaluated at temperatures of 4.2 K, 20 K and 30 K. Based on a simple model for SCFs and remnant trapped fields for a short and straight CC, the variations for a CC are formulated. The experimental results of SCFs for superimposed CCs elucidated that a SCF for each CC interacts with other SCFs.
