Developed by engineers at the University of Leeds, the robot can generate high-resolution three-dimensional ultrasound images ...

Some animals also navigate using the earth’s magnetic field. From the idea that there may be some relationship with these two things, this experimental earthquake detector was born. [ ...

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.

Engineers at the University of Leeds have developed a tiny magnetic robot that could revolutionize early cancer detection.

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

A Very Low-Frequency (VLF) detector uses two coils, one to emit and one to receive. They are overlapped just enough so that the reception coil can’t see the emission coil’s magnetic field.

The external magnetic field modulates the inductance of the loop ... The high sensitivity of SQUIDs allows for the detection of deep and subtle magnetic anomalies, aiding in the exploration and ...

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 ...
