The Y-7 Yoke offers versatility and powerful performance in a lightweight Yoke, providing either AC or DC magnetic fields in ferro-magnetic materials. The Y-7’s rugged construction and high performance make it ideal for hand-held magnetic particle inspection when performance and reliability of test equipment is critical. The Y-7 Yoke provides either a constant AC field to reveal surface defects or a pulsed DC field for revealing bothsurface and near surface defects.
