High-precision magnetic field measurement achieved with atom-based sensors
Researchers at the University of Colorado Boulder (CU Boulder) have made a significant advance in magnetic field measurement.
Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...
Recently the MagQuest competition on improving the measuring of the Earth’s magnetic field announced that the contestants in the final phase have now moved on to launching their satellites within the ...
Illustration shows how a smartphone magnetometer can measure a host of biomedical properties in liquid samples using a magnetized hydrogel. Nearly every modern cellphone has a built-in compass, or ...
