Biomagnetism is a science in which magnetic fields produced by organs or by magnetic contaminants of the body are studied. The science of Biomagnetism applies a technology that was originally developed for the measurement of extremely small magnetic field in physics. Health is determined by the electromagnetic vitality of the cells to maintain the perfect chemical balance. Properly designed bio-magnetic field can dynamically manipulate the electrical charge of the cellular tissue back to a normal healthy condition thereby return to health. The application of Biomagnetism is very wide. It can detect storage of iron in liver, particles in lungs, brain studies, heart functions etc. Biomagnetism is a boon for medicine. Biomagnetism fields result from currents or magnetization of biological tissues. Biomagnetism helps in brain study, measurement of iron concentration in liver, measurement of magnetic particles in lungs and study of heart functions.
