With increased pressure on the core syllabus from subjects relating to new technologies it is more important than ever that students receive exposure to the fundamental areas of electrical engineering science. In this respect electromagnetism is pre-eminent, and this book has been written to provide all technologists with a concise introduction to the diversity and utility of this subject.Because of its great advantage in conciseness of presentation, vector calculus is introduced at an early stage and used throughout. The emphasis, however is not mathematical, but is based upon an understanding of physical principle.The book presents a broad topic in a concise form that is most appropriate to electrical engineers who may not specialise in this area.
