Book Description
The Committee to Assess the Current Status and Future Direction of High Magnetic Field Science in the United States was convened by the National Research Council in response to a request by the National Science Foundation. This report answers three questions: (1) What is the current state of high-field magnet science, engineering, and technology in the United States, and are there any conspicuous needs to be addressed? (2) What are the current science drivers and which scientific opportunities and challenges can be anticipated over the next ten years? (3) What are the principal existing and planned high magnetic field facilities outside of the United States, what roles have U.S. high field magnet development efforts played in developing those facilities, and what potentials exist for further international collaboration in this area? A magnetic field is produced by an electrical current in a metal coil. This current exerts an expansive force on the coil, and a magnetic field is "high" if it challenges the strength and current-carrying capacity of the materials that create the field. Although lower magnetic fields can be achieved using commercially available magnets, research in the highest achievable fields has been, and will continue to be, most often performed in large research centers that possess the materials and systems know-how for forefront research. Only a few high field centers exist around the world; in the United States, the principal center is the National High Magnetic Field Laboratory (NHMFL). High Magnetic Field Science and Its Application in the United States considers continued support for a centralized high-field facility such as NHFML to be the highest priority. This report contains a recommendation for the funding and siting of several new high field nuclear magnetic resonance magnets at user facilities in different regions of the United States. Continued advancement in high-magnetic field science requires substantial investments in magnets with enhanced capabilities. High Magnetic Field Science and Its Application in the United States contains recommendations for the further development of all-superconducting, hybrid, and higher field pulsed magnets that meet ambitious but achievable goals.

Book Description
• The complete guide to magnetotherapy--the treatment that promises to revolutionize 21st-century medicine. • Magnet therapy has been used by more than 100 million people worldwide. • Clinical studies show magnet therapy to be an effective treatment for back pain, insomnia, high cholesterol and blood pressure, and many other ailments. The recent discovery of magnetic receptors in the human brain has confirmed what the ancient Chinese, Indians, Egyptians, and Greeks always knew: that human beings are strongly influenced by the Earth's magnetic field, and that by subtly altering our own energy fields with magnets we can restore proper balance to our body systems. This science of magnetotherapy has already been successfully used by more than 100 million people in the United States and around the world. Numerous scientific studies show that many cases of stiff shoulders, back, or neck, unexplained chest pain and frequent headaches, as well as insomnia and general fatigue are actually caused by what is known as Magnetic Deficiency Syndrome, and double-blind tests reveal that magnets have brought rapid relief in 90 percent of these cases. Magnet Therapy presents the history and science of this fascinating subject, explaining why magnets increase oxygenation in the blood, lower cholesterol and blood pressure, reduce pain, enhance cellular regeneration, and may even inhibit tumor growth. The authors detail methods for treating symptoms ranging from asthma to toothaches and weigh the benefits of magnetic necklaces, magnetic belts, and magnetized water, as well as traditional bipolar magnets. For devotees of alternative medicine, Birla and Hemlin explain how magnetotherapy fits into the context of other practices, such as Ayurveda and traditional Chinese medicine, and how it can be used in conjunction with acupuncture, massage, and other therapies. Complete with case studies and resource listings, Magnet Therapy is the comprehensive guide to what promises to be the next medical revolution.

Book Description
Milo Brewster, a nine-year-old magnet, notices that he has many unwanted things stuck to him, and this does not feel good. Milo begins to observe other magnets in his neighborhood, at school, and even at home. He notices that some magnets have more wanted things stuck to them than he does. Milo sets out, determined to get the answer to his question: How and why do unwanted things stick to magnets? He asks everyone he knows and gets some very surprising answers! All the characters in Unwanted Things are horseshoe magnets. Unwanted Things helps children understand how wanted and unwanted things are attracted into their lives, and it explains in a way they can relate to how the law of attraction works.

Book Description
Rapidly Solidified Neodymium-Iron-Boron Permanent Magnets details the basic properties of melt spun NdFeB materials and the entire manufacturing process for rapidly solidified NdFeB permanent magnets. It covers the manufacturing process from the commercial production of the melt spun or rapidly solidified powder, to the production and properties of both isotropic bonded Nd and hot deformed anisotropic NdFeB magnets. In addition, the book discusses the development and history of bonded rare earth transition metal magnets and the discovery of the NdFeB compound, also covering melt spun NdFeB alloys and detailing the magnetization process and spring exchange theory. The book goes over the production of melt spinning development, the operation of a melt spinner, the processing of melt spun powder, commercial grades of NdFeB magnetic powder and gas atomized NdFeB magnetic powders. Lastly, the book touches on the major application and design advantages of bonded Nd Magnets. - Features a unique perspective as the author is not only the inventor of NdFeB magnetic powder, but also played a key role in developing many of the technologies covered - Provides a comprehensive look at the history, fundamental properties, production processes, design and applications of bonded NdFeB magnets - Includes discussion of the rare earth supply challenge, politics, and systems as it impacts bonded NdFeB magnets

Book Description
Winner of the 2014 John Collier Jr. Award Winner of the Jo Anne Stolaroff Cotsen Prize Life at Home in the Twenty-First Century cross-cuts the ranks of important books on social history, consumerism, contemporary culture, the meaning of material culture, domestic architecture, and household ethnoarchaeology. It is a distant cousin of Material World and Hungry Planet in content and style, but represents a blend of rigorous science and photography that these books can claim. Using archaeological approaches to human material culture, this volume offers unprecedented access to the middle-class American home through the kaleidoscopic lens of no-limits photography and many kinds of never-before acquired data about how people actually live their lives at home. Based on a rigorous, nine-year project at UCLA, this book has appeal not only to scientists but also to all people who share intense curiosity about what goes on at home in their neighborhoods. Many who read the book will see their own lives mirrored in these pages and can reflect on how other people cope with their mountains of possessions and other daily challenges. Readers abroad will be equally fascinated by the contrasts between their own kinds of materialism and the typical American experience. The book will interest a range of designers, builders, and architects as well as scholars and students who research various facets of U.S. and global consumerism, cultural history, and economic history.
