Magnetism in Biology and Medicine

Abstract

Recent progress in the field of magnetism in biology and medicine is reviewed in this article. There are two important subjects in this field. One is the use of magnetism in the observation of biological phenomena, such as electromagnetic blood flowmeter, external observation of blood flow emf in strong magnetic field, magnetic resonance and detection of a small magnetic field of the heart. Another subject is the biological effects of static magnetic fields. Many interesting results have been reported by J. M. Barnothy and other authors, though some negative results also exist. In the theoretical interpretation of the effects of magnetic fields, there still remain many difficulties.
