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.

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 ...

Delft University's inverted pyramid Hall-effect sensor achieves improved sensitivity and offset reduction, enhancing ...

Earth's magnetic field is heavily distorted at this distance, with no clear dipolar effect. This is what makes the detection so intriguing. The waves detected at this extreme distance share ...

Scientists at the University of Aberdeen have developed an ultra-low magnetic scanner ... Centre reported that the technique, known as field-cycling imaging (FCI), could identify previously ...

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 ...
