Abstract

  Requirements for sufficient magnetizing force in MPI (magnetic particle inspection) vary considerably. When using current magnetization, the verification is fairly straightforward but when using yokes and coils, strayfields interfere with the results. The report gives recommendation for measuring the level of magnetization for different types of methods.
