Annotations languages:

The problems associated with non-destructive eddy current testing of non-ferromagnetic films and coatings. We indicate the dependence of the intensity andn of eddy s in the coating on its geometric, electromagnetic, and other parameters, as well as the interposition of the coating and eddy current measuring transducer. The design of prospective converter.
