Biomagnetics is a field of science that uses magnetic fields to study biological phenomena. It applies the principles of magnetism to the study of living organisms and their interactions with the environment. It can be used to study a range of topics, from cell biology and physiology to brain function and behavior. Biomagnetics makes use of various application techniques, such as magnetic resonance imaging, non-invasive magnetoencephalography, and transcranial magnetic stimulation, to explore the inner workings of living organisms, as well as their interactions with the external environment.
