Your own brain also emits tiny pulses of magnetic energy every time a neuron fires. But measuring what direction those fields are pointing, for precise atomic sensors in particular, can get tricky.

In mid-December of 2024, scientists officially updated the World Magnetic Model (WMM), which helps keep track of our planet’s magnetic north and its chaotic and relatively unpredictable movements.

Researchers at University of Tsukuba previously developed a method for detecting fuel cell failuress using magnetic sensors. In this study, they applied this method and developed a system for ...
