The authors have assembled an impressive array of research and statistical information on biomedical data, including clinical and controlled tests by leading physicians, supporting their conviction that magnetic devices, both electromagnetic and permanent magnets, can have a profound and positive affect on health maintenance and disease riddance. The discussions are in a narrative style. The authors discursively cover biological effects of magnetic fields, electromagnetic vs. permanent magnets, comparison of poles, case studies, and how to apply magnetotherapy for a wide variety of conditions.
