This book is a concise introduction to electromagnetic fields for students on degree and diploma courses. Physical processes and their descriptions are elucidated in words rather than mathematical symbols. Only simple differentiation, integration, and a little trigonometry are required. For this new edition there are new sections on electromechanics and high-frequency phenomena.

This is a fully revised and updated edition of a widely used introductory textbook on electromagnetism. It covers all the fundamental aspects of this important topic in electrical engineering. The approach is eminently practical and requires little mathematics other than elementary differentiation, integration, and trigonometry. It will continue to appeal to students studying this conceptually challenging but fundamental subject. New sections on electromechanics (conversion of electric and magnetic energy in mechanical energy and vice versa) and high-frequency phenomena (transmission lines, waveguides, optical fibres, and radio propagation) enhance the usefulness of the book.

John Dryden was England's most outstanding and controversial writer for the last four decades of the seventeenth century. He dominated the literary world as a satirist, a skilled and versatile dramatist, a pioneer of literary criticism, a writer of religious poetry, and an eloquent translator from the great classical poets. The present book discusses Dryden's career both chronologically and thematically, taking issue with his enemies' denigration of his integrity, and revealing him as a subtle, passionate and sceptical writer.
