NMR imaging in the earth's magnetic field
Magnetic Resonance in Medicine, 1990AbstractThe most important and very expensive part of a magnetic resonance imaging set‐up is the magnet, which is capable of generating a constant and highly homogeneous magnetic field. Here a new MR imaging technique without the magnet is introduced. This technique uses the earth's magnetic field instead of a magnetic field created by a magnet.

Journal of Navigation, 1950
The Institute has now completed two years of its existence. The papers which have been read before it during these two years have covered a wide range of subjects and have served to emphasize the many ramifications of the science of navigation. Because of the high speed of modern aircraft, air navigation presents more problems and of greater variety ...

Abstract Legendary anecdotes relate how Greco-Roman and Chinese societies may have first become aware of magnetism. For centuries it was thought to be a celestial power, but scientists learned through experimental investigations how magnetism is related to electrical currents.

The Room with the Weakest Magnetic Field on Earth
Scientific American, 2015The article discusses a room at the Technical University of Munich in Germany which is designed to contain the weakest magnetic field in the solar system. Physicists will be able to use the room for research on topics such as antimatter, magnetic monopoles, dark matter, and the role of magnetic fields in animal navigation.

Magnetic disturbances and the Earth's magnetic field
Journal of Geophysical Research, 1961An attempt is made to explain the origin of the observed magnetic field of the earth as being due to a current system circulating in the core, the current system in its turn being maintained by world-wide magnetic disturbances. The mantle behaves as a semiconductor, and the conduction electron density is given by the Boltzmann distribution law.
