    A formula for demagnetizing correction of the measured permeability of cylindrical samples is derived. The procedure for using this formula and the accurately calculated fluxmetric demagnetizing factors to treat the results of fluxmetric measurements is introduced and applied to several samples of different lengths cut from the same magnetic cylinder. The revision of ASTM A342, standard test methods for permeability of feebly magnetic materials, is explained in the appendix. © 2012 IOP Publishing Ltd.
