Abstract

PURPOSE: To provide a metal body inspecting method, in which the variation in the quantity and direction of a balanced magnetic field in a pair of magnetizers by a metal body made approachable to the inside of the magnetic field is detected to detect the approach and passage of and to inspect other conditions of the metal body.
