Electromagnetic induction imaging (EMI) is a well established imaging technique, developed over several decades. It has been widely used to assess cracks in metallic structures and to detect and ...
A pair of coils induces a magnetic field response (labeled BEC) in a low-conductivity solution contained in a petri dish, detected by a radio-frequency atomic magnetometer, based on laser manipulation ...
Researchers built a fingernail-sized magnetometer using metasurfaces that measures fields billions of times weaker than Earth's, opening new paths for quantum sensing. At the heart of the sensor is an ...
From ancient compasses to modern smartphones, magnetometers have quietly shaped how we sense and navigate the world. Let us explore the fundamentals behind these field-detecting devices. Magnetic ...
