It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor ...

Getting a magnetic field to balance on another magnetic field is about as easy as balancing a bowling ball on the tip of an ink pen. With a little help from an Arduino mega, however, [EmmaSong ...

Magnetic sensor chips are semiconductor devices that detect physical quantities using magnetic principles. They are used in mobile communications, attitude sensing and navigation, and the mapping of ...

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 ...

Magnetic field sensors are used to measure magnetic flux and/or the strength and direction of a magnetic field. They are used mainly in scientific measurement, navigation, and industrial applications.

In the laboratory: Taner Esat from Forschungszentrum Jülich. (Courtesy: Forschungszentrum Jülich / Sascha Kreklau) Researchers in Germany and Korea have fabricated a quantum sensor that can detect the ...

SiCMag is also very small— the sensor area is only 0.1 x 0.1 mm and the compensation coils are smaller than a penny. Consequently, dozens of SiCMag sensors can easily be incorporated on a ...

The limitations of diamond-based sensors, though, is that they can only detect magnetic fields when aligned in the direction of the field. If unaligned, they have large blind spots. As a result ...

Transcranial magnetic stimulation is a method to noninvasively stimulate neurons in the brain and induce immediate or long term changes in activity. Stimulation is mediated by electromagnetic ...

Many of the most popular headphones, even for listeners on a budget, use planar magnetic drivers, and for good reason: the level of detail and clarity they’re able to provide is outstanding.

Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...
