MIT Engineers Develop New Magnetic-Field Detector That is 1,000 Times More Efficient

Engineers at MIT have developed a new, ultrasensitive magnetic-field detector that is 1,000 times more energy-efficient than its predecessors. The detectors could lead to better sensors for medical imaging and contraband detection. Magnetic-field detectors, or magnetometers, are already used for all those applications. But existing technologies have drawbacks: Some rely on gas-filled chambers; others work […]
