Nearly every modern cellphone has a built-in compass, or magnetometer, that detects the direction of Earth's magnetic field, providing critical information for navigation. Now a team of researchers ...

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 ...

The magnetometer in your smartphone helps you navigate by powering the device's digital compass. Now researchers have found a way to use it to navigate body chemistry by reading your glucose levels, ...

For just over two years, a scalar magnetometer developed by Graz University of Technology (TU Graz) and the Space Research Institute (IWF) of the Austrian Academy of Sciences has been on its way to ...

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 ...

Illustration shows how a smartphone magnetometer can measure a host of biomedical properties in liquid samples using a magnetized hydrogel. Nearly every modern cellphone has a built-in compass, or ...
