摘要: A series of experiments has been carried out on the flux trapping and shielding capabilities a flat strip Nb‐Ti/Cu composite material. circular piece material from was tested in uniform field directed perpendicularly to surface sample. Profiles normal component along sample diameter were measured. The critical‐state model adapted for this geometry proved capable reproducing measured profiles. Model curves agreed well with experimental profiles generated when full critical state, only portion obtained after direction rate change magnetic reversed. adaption disk provides possible method either derive values current measurements above thin samples, or predict behavior such samples i...
