Opis

This text provides an introduction to the whole field of permanent magnetism. It contains a comprehensive but concise treatment of the fundamental theory underlying permanent magnetism, and illustrates applications with modern permanent magnetic materials. Each chapter contains worked examples to reinforce applications. Detailed mathematics and tabular data on material properties are treated in the appendices.
