Let this surveillance detector keep you safe, sweeping for hidden cameras or other trackers in any place you stay.

A team of researchers has developed a pioneering 3-axis Hall-effect magnetic sensor based on an inverted pyramid structure.

We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the ...

A Superconducting Quantum Interference Device (SQUID) is an extremely sensitive magnetometer that measures very subtle magnetic fields. It exploits the quantum mechanical properties of ...

A tiny magnetic robot that can take 3D scans from deep within the body and could transform early cancer detection has been ...

After over 35 years of trying, NASA finally confirmed Neptune has auroras. They did this when astronomers were able to ...

Scientists at the University of Aberdeen have developed an ultra-low magnetic scanner, which can perform MRI scans without the need for intravenous contrast agents and with unprecedented precision.

A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction ...
