It hasbeen a long-held belief in scientific circles that many creatures navigateacross land, through water, and through the skies using the Earth’s magnetic field forguidance. Now scientists and ...

The human body is controlled by electrical impulses in the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could use to diagnose various ...

This new magnetic sensor measures position and rotation of both non-ferrous and ferrous metals alike. The depth of detection can be varied by changing the excitation frequency. High resolution is ...

Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain. Researchers have developed a light-based technique ...

New MFxM magnetic proximity switches detect magnetic fields over large distances up to 60 mm. These sensors can be used effectively in applications where the target is located behind a wall of ...

The Debye effect could be used hunt submarines using the magnetic signatures of their wakes. Seawater is salty, full of ions of sodium and chlorine. Because those ions have different masses, any nudge ...

The types of magnetic sensors that are currently available. How the magnetic sensors work. Applications for the different magnetic sensors. Position sensors enable a variety of functions and controls ...

Biomagnetism applications A novel magnetic gradiometer can record human brain activity and detect cardiac activity in the presence of external magnetic field disturbance. (Courtesy: ...
