Experimental studies of the reflection coefficient of a film that visualizes magnetic fields in the zone of a flaw during testing of ferromagnetic objects

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 i...

Description
Summary: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.
