Basic Introduction to Bioelectromagnetics, Third Edition, is a primary source for medical technologists and life scientists seeking to understand how electromagnetic fields interact with the body, and how they are used in medical applications. Instead of the complex math commonly used when analyzing electromagnetics, this book uses graphical methods and simple equations. The third edition is updated with color graphics that show the fields in bright, clear colors. Each concept is presented with an associated discussion and application, including MRI, NMR, hyperthermia, neural stimulation, ultrasound, and cardiac pacing/defibrillation.
Offering a simplified explanation of a very complex subject, this third edition provides an accessible introduction for life scientists and medical technologist on how EM fields work, what controls them, and the factors important to experimental setups and medical applications.
This qualitative and illustrative book:
- Covers the entire frequency spectrum from direct current (DC) up through optical frequencies.
- Includes more than 200 illustrations, 65 in color, and 40 medical applications.
- Incorporates examples from real-world applications to explain concepts.
- Concentrates on the qualitative explanation of the key concepts, fundamental principles, and characteristic behaviors of EM fields, without complicated mathematics.
- Offers practical rules of thumb to understand real situations.
- Requires only a background in algebra, in contrast to typical EM books that require vector calculus and differential equations.

'This book presents a complicated topic in a simple way using examples and illustrations to provide general intuition on the important concepts of Bioelectromagnetics. The reader can grasp the fundamental concepts of biolelectromagnetics without the requirement for a strong background in vector calculus and partial differential equations. This book is perfect for people working in the life science world that want to understand the fundamental concepts behind the electromagnetic tools they use in their work.'
- Dr. Rock Hadley, Research Assistant Professor, University of Utah
"The book is unique in terms of its content; it is simple with minimal mathematics. It targets "anybody" who is interested in bioelectromagnetics and who wants to know "something" about electromagnetics."
- Professor Levent Sevgi, İstanbul OKAN University
"The main strength of this text, as its title suggests, is that it does not assume expertise in electromagnetics. Several other texts on bio-electromagnetics assume from the reader in-depth knowledge of electromagnetic theory and are hence difficult to use in undergraduate courses. This is the first text, to my knowledge, that is undergraduate-friendly and that makes this non-trivial topic approachable… for an instructor who wants to introduce undergraduates to bioelectromagnetics, this text makes the course preparation easier and will be a valuable resource for the students."
- Professor Milica Popovich, McGill University
"The authors clearly explain the underlying concepts and theories important to electromagnetics without relying on detailed equations. These explanations are supported by a series of scenarios that illustrate the key points effectively. The scenarios are also designed to provide insight into practical applications. This approach allows the authors to emphasize the important aspects of fields to consider, and to discuss a variety of real-world applications."
