Abstract

The invention concerns an arrangement for detecting adequacy of magnetic flux produced by a magnetization yoke in magnetic flaw detectin when an inspected ferromagnetic object is magnetized. The arrangement consists of a measurement ring 2 that is positioned around one of the poles of magnetization yoke 1 near an inspected surface and whose indicator L1... L8 displays the adequacy of the magnetic flux. A method is also presented for controlling the arrangement based on measurement of lifting force and the induced voltage. <IMAGE>
