Fluxgate magnetometers represent a cornerstone technology in magnetic field measurements, utilising a ferromagnetic core excited by an alternating current to gauge weak, quasi‐stationary magnetic ...

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 ...

MAGNETIC COMPASSES have guided sailors for centuries, but a compass tells you only in which direction you are pointing, not whereabouts you are. A new form of magnetic navigation being developed by ...
