mittepurustav katse, mille korral kasutatakse hälvingute ilmutamiseks kontrastvärvaineid ja ferromagnetilisi metallipulbreid, nt raudoksiidi (vt magnetpulberkatse; vrd magnetfluorestsentspulberkatse), nondestructive test for determining flaws with magnetic particles coated with contrast color to increase the visibility of results (see: magnetic particles test; compare: magnetic fluorescent particles test)
