"Biomagnetics is an interdisciplinary field where magnetics, biology, and medicine overlap. Recent advances in biomagnetics have enabled us not only to detect extremely weak magnetic fields from the human brain but also to control cell orientation and cell growth by extremely high magnetic fields. Pulsed magnetic fields are used for transcranial magnetic stimulation of the human brain, and both high-frequency magnetic fields and magnetic nanoparticles have promising therapeutic applications for treatments of cancers and brain diseases such as Parkinson's and Alzheimer's diseases. On the imaging front, magnetic resonance imaging (MRI) is now a powerful tool for basic and clinical medicine. New methods of MRI based on the imaging of impedance of the human body, called impedance MRI, and the imaging of neuronal current activities in the human brain, called current MRI, are also being developed. To understand the most advanced technologies in biomagnetics, basic sciences such as physics, biology, chemistry, magnetics, electromagnetics, physiology, and neurophysiology are important to build a foundation and construct bridges between science and medicine. These basic items are included in this book"--
