  文件詳細(xì)說明:
  This paper reports an interlaboratory study on two typical DC magnetic test methods, ballistic and scanning test method, respectively. By measuring 10 different kinds of soft magnetic materials using five computerized DC hysteresis graphs,discrepancies of the result is witnessed. Phase shift also exists in DC magnetic test, which causes significant error in themeasured static hysteresis loss. But different from the AC magnetic test, the phase drift is caused by drift of flux meter, whichcan’t be eliminated by post-measurement adjustment routine in the commercial magnetic instrument. By analyzing intrinsic
deficiency of scanning test method, which is adopted by most instrument manufacturers, ballistic test method could be apromising method for DC magnetic measurement.
