Biomagnetism

Biomagnetism is the study of the magnetic fields produced by living organisms and the effects of external magnetic fields on biological systems. This field of research encompasses two main aspects: 1. **Magnetic Fields in Living Organisms**: All living entities, including humans, generate weak magnetic fields due to the electrical activity of cells, particularly those involving ion movements in nerves and muscles. For example, the heart generates a magnetic field as a result of the rhythmic electrical impulses that control heartbeats.
