Tiny, Atom-based Detector Senses Weak Magnetic Fields

Facebook X LinkedIn Email
GAITHERSBURG, Md., Jan. 5 -- A low-power magnetic sensor about the size of a grain of rice that can detect magnetic field changes as small as 50 picoteslas -- a million times weaker than the Earth's magnetic field -- has been demonstrated by researchers at the National Institute of Standards and Technology (NIST). The device can be powered with batteries and is about 100 times smaller than current atom-based sensors with similar sensitivities, which typically weigh several kilograms (about six pounds). The new magnetic sensor is based on the principles of an NIST chip-scale atomic clock,...Read full article
