Overview

Electricity and Magnetism (E&M) underlies many lifesaving medical devices, such as magnetic resonance imaging scanners, neural stimulators, and heart pacemakers. But E&M also attracts its share of bogus health claims, such as biomagnetic therapy. How do you separate the good from the bad? Sometimes it’s not easy: experiments are prone to artifacts, theories are limited by assumptions, and clinical trials can result in ambiguities. In this book, the author separates the wheat from the chaff, showing which applications of E&M are bogus and which are not. This book takes the reader on a tour through a range of fascinating phenomena, from effects that are constant in time at one extreme, such as transcranial direct current stimulation of the brain, to the millimeter-wave whole-body scanners which are familiar to frequent flyers at the other. Along the way, the author looks in depth at the dispute about power line magnetic fields and leukemia, a case study in what can go wrong when dubiousclaims inflame unjustified fears. The debate about cell phones and brain cancer still rages today, particularly for the microwave frequencies encountered with new 5G technology. Recently, the so-called Havana Syndrome has been attributed to microwave weapons, but the underlying biophysics of such weapons is unclear. For all these encounters with electricity and magnetism, the author, an eminent biophysicist, uses science and evidence to sort out fact from fantasy. This book is aimed at general readers who want to make sense of the mysterious and often controversial ways in which E&M interacts with the human body. It is also ideal for students and professionals in bioscience and health-related fields who want to learn more without getting overwhelmed by theory.

This book is an essential reference that would be a great addition to every skeptic's bookshelf. It summarizes the evidence about the health effects of electromagnetism and provides ammunition for debunking pseudoscientific rumors. It's short, inexpensive, well-written, and full of interesting facts. I was particularly intrigued to learn that an electric eel has its own Twitter account.

Author Information

Bradley J. Roth was a Professor in the Physics Department at Oakland University, Michigan, for 22 years before his retirement in 2020. He received his degree from the University of Kansas before getting his MS and PhD from Vanderbilt University. He conducted research as part of the Biomedical Engineering and Instrumentation Program at the US National Institutes of Health, Maryland, after which he returned to Vanderbilt as the Robert T. Lagemann Assistant Professor of Living State Physics before joining the faculty at Oakland University. He is a co-author of the textbook Intermediate Physics for Medicine and Biology, now in its 5th edition (Springer, 2015), and was elected as a fellow of the American Physical Society Division of Biological Physics in 2006 for his theoretical and numerical studies of bioelectric and biomagnetic phenomena, especially for his contributions to the bidomain model of the heart.
