The Eddy Current Process at a Glance. ... Changes or variations in the eddy currents are caused by defects in the tube wall, such as near-surface cracks and inconsistencies in metal thickness.

Eddy current testing is confined to materials that conduct electricity and therefore cannot be applied to plastics. In some instances, eddy current and ultrasonic tests are used in tandem, with eddy ...

The stronger the eddy currents, the more likely they are to trigger extreme temperatures deeper down. Eddy currents are the main driver for nearly half of all deep ocean heat waves and cold spells.

Ida passed over an ocean eddy, a shallow swirl of warm water that spun off the Loop Current, as it rapidly intensified into a Cat 4 hurricane before making landfall in Louisiana in 2021.
