During the years since this book was first published in 1993 there have very few developments in the technology of magnetic particle inspection apart from improvements in instrumentation which has made the measurement of peak values of time varying currents practicable. The major changes have arisen from health and safety and environmental concerns. These involve chemicals and exposure of personnel to air-borne electromagnetic fields and long wave ultraviolet (UY.A). The changes in the acceptability of certain volatile halogenated hydrocar bons which led to the banning of 1, 1, 1 thichloroethane in 1995 were evident in 1993. The present discussions concerning the emissions of volatile organic compounds (VOCs) in general was also current and has now reached a stage where the effects of these deliberations will become evident over the next few years. Concerns over the exposure of personnel to airborne electromagnetic fields has been current for some years as has discussions to the effects of long wave ultraviolet (UY.A) on human skin. Recommendations as to maximum permit ted exposures over periods of time to both of these phenomena have been put forward and will doubtless form the basis of future legislation on the matter. A number of new specifications have appeared notably EN (European) and ISO specifications and some of these are still in preparation. Generally their impact will be minimal since these specifications are largely derived from existing documentation.

"Magnetic Particle Inspection: Techniques, Applications, Interviews Q&A, and Glossary" is a complete guide to the non-destructive testing technique of magnetic particle inspection (MPI). This NDT book covers the fundamental principles of MPI, including the types of magnetic fields used, the properties of magnetic particles, and the various types of equipment used in the process. In addition to the basic principles, the magnetic particle testing book also covers advanced topics such as selecting the appropriate current for wet or dry inspection, the use of UV light in MPI, and the demagnetization process. To provide readers with practical insights into the application of MPI, the magnetic particle inspection book includes interviews with experts in the field, who share their experiences and tips on best practices. Finally, the book features a glossary of MPI terms and definitions, making it a valuable reference for both beginners and experienced practitioners. Whether you are new to the field of Magnetic testing or looking to enhance your existing knowledge, "Magnetic Particle Inspection: Techniques, Applications, Interviews Q&A, and Glossary" is an essential resource that will help you develop a comprehensive understanding of this important non-destructive testing technique.

This volume provides a comprehensive overview of recent developments in magnetic particle imaging (MPI), a novel imaging modality. Using various static and oscillating magnetic fields, and tracer materials made from iron oxide nanoparticles, MPI can perform background-free measurements of the particles’ local concentration. The method exploits the nonlinear remagnetization behavior of the particles and has the potential to surpass current methods for the detection of iron oxide in terms of sensitivity and spatiotemporal resolution. Starting from an introduction to the technology, the topics addressed include setting up an imaging device, assessment of image quality, development of new MPI tracer materials, and the first preclinical results. This is the first book to be published on magnetic particle imaging, and it will be an invaluable source of information for everyone with an interest in this exciting new modality.
