Installation for Biomagnetism Studies

Biomagnetism and vision.

o,ne more example of how advances in one field of science may lead to advances in other, distantly related fields is the recent use of superconducting instruments in the study of the visual system. At the heart of these instruments is the superconducting quantum interference device (SQUID), which is exquisitely sensitive to weak magnetic fields. These devices do not depend upon Faraday inductio...

Boston and the history of biomagnetism.

It is of historical interest that our latest conference, Biomag 2004 (14 International Conference on Biomagnetism), is taking place in Boston. There are two historical events to consider. First, because the initial biomagnetic SQUID measurements were made about 3 km away in Cambridge (in 1969), this Boston area seems to be called "the birthplace of biomagnetism" [Science, 1989], so in a sense w...

Bacterial Biomagnetism and Geomagnetic Field Detection by Organisms

The Earth is a magnet. Its dipole character from e results massive currents within the molten portion of its core. These currents, presumably by gravitational in driven i energy, induce, the manner of a self-sustaining dynamo, a global dipolar magnetic field with t a magnitude of rouehly g 0.7 gauss at the gne ti poles. Although the ancient Chinese were familiar with the polar alignment of magn...
