Book excerpt: The study of electromagnetic fields in the treatment of various diseases is not a new one; however, we are still learning how magnetic fields impact the human body and its organs. Many novel magnetic materials and technologies could potentially transform medicine. Magnetic Materials and Technologies for Medical Applications explores these current and emerging technologies. Beginning with foundational knowledge on the basics of magnetism, this book then details the approaches and methods used in the creation of novel magnetic materials and devices. This book also discusses current technologies and applications, as well as the commercial aspects of introducing new technologies to the field. This book serves as an excellent introduction for early career researchers or a reference to more experienced researchers who wish to stay abreast of current trends and developing technologies in the field. This book could also be used by clinicians working in medicine and companies interested in establishing new medical technologies. Each chapter provides novel tasks for future scientific and technology research studies. - Outlines the basics of magnetism for enhanced understanding of its applications in medicine - Covers novel magnetic devices as well as technologies still under development, including magnetic brain stimulation, biosensors, and nanoparticles for drug delivery - Explores commercial opportunities and obstacles to market entry for new magnetic materials and technologies for the medical field
