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 ...

We just got a couple images from one of our Apple ninjas and it appears to show a compass option in one of the debugging menus. Our source says this is obviously for a built-in magnetometer in the ...

Researchers from the National Institute of Standards and Technology (NIST), Boulder, Colorado, say a smartphone compass could be used to analyze biomarkers in body fluids — blood, sweat, urine, or ...

Many systems currently available on the market depend on digital magnetometers for providing heading measurements of a manned or unmanned platform. However, the majority of these platforms (e.g.

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 ...
