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

Your own brain also emits tiny pulses of magnetic energy every time a neuron fires. But measuring what direction those fields are pointing, for precise atomic sensors in particular, can get tricky.

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 ...

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

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 ...
