Electrical and magnetic methods of nondestructive testing
Abstract
Attention is given to electrical and magnetic methods of nondestructive testing, with emphasis on the widely used eddy current and magnetic flux leakage methods (including particle inspection). Other techniques, such as MW and AC field applications, are also examined. Theoretical analyses relating to the various methods are discussed, with emphasis on electrical conductivity and resistivity, dielectric materials, electromagnetism, circuit networks, ferromagnetic materials, and electromagnetic radiation. Consideration is also given to eddy current principles and methods, as well as MW methods of testing.
