This book reveals the magnificent landscape paintings of the Group of Seven and their associates and explores how they contributed to Canada's modern cultural identity. The early decades of the 20th century were marked by artistic, economic, and social transformation in Canada and around the world. Starting in Toronto, a group of young modern artists, including Tom Thomson and Lawren S. Harris, and Emily Carr in British Columbia, desired to create a new painting vocabulary for the young nation coming into its own cultural identity. They turned away from city life and explored Canada's landscape, painting sublime vistas, monumental rivers, ancient forests around the great lakes, the mighty Rocky Mountains, and the arctic tundra, determined to break away from European stylistic traditions. Together, their paintings imagined a mythical Canada, expansive and rugged, that added to their country's growing sense of national pride. Featuring paintings, sketches, photographs, film stills, and documentary material, this catalog examines the language of Canadian modernism. It also includes essays and interviews that offer contemporary indigenous perspectives on the impact of industry on nature, issues surrounding national identity, and modern Canadian landscape painting. This generously illustrated book critically reviews Canada's modernism in art history.

This book covers the fundamentals of magnetism and the basic theories and applications of conventional magnetic materials. In addition there is extensive discussion of novel magnetic phenomena and their modern device applications. The book starts with a review of elementary magnetostatics and magnetic materials, followed by a discussion of the atomic origins of magnetism. The properties and applications of ferro-, ferri, para-, dia- and antiferro-magnets are surveyed, and the basic theories that describe them are outlined. The final part of the book focuses on novel magnetic phenomena, and on magnetic materials in modern technological applications. Based on a course given by the author in the Materials Department at UC Santa Barbara, the book is targeted at graduate and advanced undergraduate students as well as researchers new to the field. Highly illustrated, containing numerous homework problems and worked solutions, this book is ideal for a one semester course in magnetic materials.

Electrical and Magnetic Methods of Nondestructive Testing presents a comprehensive account of the electrical and magnetic methods of nondestructive testing (NDT). The book begins with a discussion of the requirements for NDT and the criteria for the choice of a given method, followed by a summary of the general theory relating to electrical and magnetic testing techniques. Subsequent chapters discuss specific methods, including eddy current and flux-leakage techniques and microwave and potential drop methods. The appendix provides some useful programs for eddy current impedance analyses. These programs are in BASIC and can be run on PCs.

Magnetic: The Art of Attracting Business is a look at how consistently successful businesses are able to attract a steady and ever-increasing flow of customers. This innovative text examines a range of simple, powerful strategies that businesses of any size or type can use to attract new customers. The key is to do those things that harness the power of the single most important factor in buying decisions: positive word of mouth and referrals from happy existing customers. Magnetic businesses are intentional, strategic, and focused on creating positive experiences that become the stories their customers tell about them. Whether on the internet or face to face, it's what satisfied customers say about you that is the most powerful driver of growth for your business. Becoming Magnetic and attracting business, truly is an art, rather than a science, because every business is different, and uses a unique combination of strategy, people, and purpose to achieve success and growth. There is no one-size-fits-all formula, but with creativity and focus, any business can create a powerful revenue growth engine that continuously works to build and sustain success. Learn how to match successful growth strategies with your people, purpose, and culture to create your own unique 'magnetism' to attract business. Discover the simple, powerful keys to growth used by a range of market leading businesses, from a snowboard manufacturing startup company and a website design professional to a minor league baseball team and an family owned upscale grocery store. All of them utilize ideas that you can put to work immediately in your business to become Magnetic. Create a magnetic mindset in your people that leads not only to happier customers who refer others to you, but to more satisfied employees who help attract and recruit great new employees to keep your momentum going. Simplify and clarify how you think about your business to have your entire team become more focused, efficient, and effective in doing those few vitally important things that matters most in driving growth and sustaining success.

The book deals with methods for the description and design of electromagnetic components. Both linear and nonlinear components are covered. For electrical simulations the necessary equivalent circuit diagrams are derived and a general methodology is developed. Possible influences on properties via material selection, winding design and premagnetisation of sections are treated. Measurement characterization, modeling, possible errors and model limits are dealt with extensively. In the last chapter examples are discussed.

Magnetic Particle Imaging (MPI) is a novel imaging modality. In MPI superparamagnetic iron oxide nanoparticles are used as tracer materials. The volume is the proceeding of the 2nd international workshop on magnetic particle imaging (IWMPI). The workshop aims at covering the status and recent developments of both, the instrumentation and the tracer material, as each of them is equally important in designing a well performing MPI. For instance, the current state of the art in magnetic coil design for MPI is discussed. With a new symmetrical arrangement of coils, a field-free line (FFL) can be produced that promises a significantly higher sensitivity compared with the standard arrangement for a FFP. Furthermore, the workshop aims at presenting results from phantom and pre-clinical studies.

This concise book presents the basic concepts of magnetism and magnetic properties pertinent to permanent magnetic materials. Emphasis is placed on hexaferrite materials for permanent magnet applications, with M-type ferrites as the focal point. The relatively high metallicity of magnetic materials for practical applications imposes limitations for their efficient use. Accordingly, magnetic oxides with ferromagnetic properties emerged as the most widely used magnetic materials for practical applications, owing to their characteristic high resistivity and low eddy current losses, chemical stability, simplicity of production in mass quantities, and other favorable characteristics. An important class of these oxides is the class of hexagonal ferrites developed in the early 1950’s, which dominated the world market of permanent magnet applications since the end of the 1980’s. Among these ferrites, the magnetoplumbite (M-type) hexaferrite, is produced nowadays in large quantities at very competitive low prices, thus providing the permanent magnet market with probably the most cost-effective magnetic material.

High-field magnetsâ€"those that operate at the limits of the mechanical and/or electromagnetic properties of their structural materialsâ€"are used as research tools in a variety of scientific disciplines. The study of high magnetic fields themselves is also important in many areas such as astrophysics. Because of their importance in scientific research and the possibility of new breakthroughs, the National Science Foundation asked the National Research Council to assess the current state of and future prospects for high-field science and technology in the United States. This report presents the results of that assessment. It focuses on scientific and technological challenges and opportunities, and not on specific program activities. The report provides findings and recommendations about important research directions, the relative strength of U.S. efforts compared to other countries, and ways in which the program can operate more effectively.
