Earth's magnetic field, a familiar directional indicator over long distances, is routinely probed in applications ranging from geology to archaeology. Now it has provided the basis for a technique which might, one day, be used to characterize the chemical composition of fluid mixtures in their native environments. Researchers have carried out nuclear magnetic resonance experiments using an ultra-low magnetic field comparable to Earth's magnetic field.
