The World Magnetic Model (WMM) has long been the standard for mapping Earth’s magnetic field, but the 2025 update offers a significant upgrade. Resolution has improved from 2,050 to 186 miles ...

“The way the model is built, our forecast is mostly an extrapolation given our current knowledge of the Earth’s magnetic field.” The scientists released two models on December 17: the ...

An AI model can scan your brain with non-invasive equipment and convert your thoughts into typed sentences — with no implants ...

USTC researchers created a long-lived Schrödinger-cat state, boosting quantum metrology and precision measurements. Their ...

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 ...

Just hours after touching down on the surface of the moon on March 2nd aboard Firefly Aerospace's Blue Ghost 1 lander, the ...

Scientists have long been fascinated by special magnetic materials where atoms arrange their spins in a spiral pattern. These ...

Engineers have developed a new computational approach to accurately model and predict the properties of a class of magnetic molecules called chiral helimagnets. Their work could accelerate the ...

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 ...
