Dependence of the Detectability of Flaws on the Distribution of the Magnetizing Field in the Vicinity of a Flaw
Source abstract
Abstract
It is shown that the flaw detectability of the magnetic-powder inspection method depends on the ratio of the normal Hn and tangential Ht components of the field in the flaw's vicinity and that Hn/Ht < 3 is a condition that ensures the detectability of surface flaws.
