A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

Have you ever wondered how a magnetometer works? We sure have, which was why we were happy to stumble upon this article on simple homebrew fluxgate magnetometers. As [Maurycy] explains, clues to how a ...

Richard Luxton first studied clinical chemistry in the National Health Service for thirteen years at the Bristol Royal Infirmary before moving to the Institute of Neurology in London. At the ...

Did the ancient Greeks have outside toilets? Up-to-date archaeologists interested in esoteric problems heard last week about a handy way of finding answers to such questions—for a latrine’s humus-rich ...

They’ve flown on high-profile interplanetary and more modest low-Earth-orbiting missions, but in all cases the ubiquitous fluxgate magnetometers that scientists use to measure the intensity of a ...

In one of the earliest magnetic measurements, primitive mariners used lodestones—magnetized pieces of magnetite—to determine the earth’s magnetic field. Today, thousands of applications require the ...

When you get an MRI scan, the machine exploits a phenomenon called nuclear magnetic resonance (NMR). Certain kinds of atomic nuclei—including those of the hydrogen atoms in a water molecule—can be ...
