A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

Scientists know well how conventional materials conduct heat. However, things are not as straightforward under extreme ...

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

Amplification of the fields allows the sensors to detect ... Fawaz suspected the accompanying magnetic fields would be useful where microwave radiation is used to trigger a field for the ...

A trio of physicists from Princeton University, CIT's Jet Propulsion Laboratory and Spectral Sensor Solutions, all in the U.S ...

Scientists in Spain have created tiny flower-shaped structures that can boost magnetic fields in a very small area. These ...

The average Hackaday reader likely knows, at least in the academic sense, what a magnetic field looks like. But as the gelatinous orbs in our skull can perceive only a tiny fraction of the EM ...

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 ...

A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the ...
