Abstract:The character of changes in the light-reflection coefficient in the zone of indicator patterns of flaws on a magnetic-field-visualizing film was determined during magnetic testing of ferromagnetic plates. The flaw detection in specimens was performed in an applied field directed in parallel to the inspected surface. External light radiation was directed perpendicular to the specimen surface and the magnetic-field-visualizing film that were placed on it.
