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 ...

JW Fishers has specialized in the design and manufacture of underwater search equipment for almost 50 years. The Proton 5 is a top performing, microprocessor driven, marine magnetometer detection ...

The small variations in the Earth’s magnetic field are being measured using this proton precession magnetometer (PPM) which detects the ferrous objects on land and at sea. To map the positions of ...

Magnetometers and gradiometers are being used increasingly in monitoring roles (i.e. to monitor atmospheric magnetic disturbances, volcanoes or earthquakes). The Overhauser magnetometer, with its ...
