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

Researchers have now unlocked the secret to doing so with a tabletop quantum sensor that can capture magnetic fields with ...

Like ZrTe₅: it combines a rare set of non-trivial electronic properties, making it potentially relevant for high-precision electronics applications and magnetic-field sensor technologies.

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 ...
