This book is intended to help satisfy an urgent requirement for up-to- date comprehensive texts at graduate and senior undergraduate levels on the subjects in non-destructive testing (NDT). The subject matter here is confined to electrical and magnetic methods, with emphasis on the widely used eddy current and magnetic flux leakage methods (including particle inspection), but proper attention is paid to other techniques, such as microwave and AC field applications, which are rapidly growing in importance. Theoretical analyses relating to the various methods are discussed and the depths of presentation are often governed by whether or not the information is readily available elsewhere. Thus, for example, a considerable amount of space is devoted to eddy current theory at what the author considers to be a reasonable standard and not, as usually experienced, in either a too elementary manner or at a level appreciated only by a postgraduate theoretical physicist. The inclusion of the introductory chapter is intended to acquaint the reader with some of the philosophy of NDT and to compare, briefly, the relative performances of the more important methods of testing.

This fully revised and thoroughly updated new edition of Electrical and Magnetic Methods of Non-destructive Testing provides a comprehensive account of the subject. The requirements for non-destructive testing are debated along with the criteria for the choice of a given method. This is followed by a summary of the general theory relating to electrical and magnetic testing techniques and a discussion of specific methods. New features of this edition include: coverage of recent developments in magnetic methods of testing, such as SQUID magnetometry and Barkhausen emission testing; a new chapter exploring the latest developments in eddy current testing such as improvements in probe design, the use of neural networks and defect imaging, especially with the use of magneto-optic method (MOI); a more detailed discussion of RADAR and potential drop methods of testing, especially of concrete structures. Electrical and Magnetic Methods of Non-destructive Testing will be of great value to any engineer, scientist or postgraduate student working in this field.
