Biomagnetism is the study of magnetic fields produced naturally by the body. Like other types of magnetism, biomagnetism arises from electrical currents, such as ionic current generated by brain or heart activity, and from magnetic materials, such as iron compounds in the liver.

Biomagnetism can provide important information about bodily function. The most active area of biomagnetism research is magnetoencephalography (MEG), a functional brain imaging technique. In addition to MEG, our group is especially interested in fetal applications; i.e. detection of magnetic signals from the fetal heart and brain.
