Imagine waking up one morning to a world where compasses point south instead of north, where auroras shimmer across the ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed.

Imagine crossing vast oceans, soaring across continents, or tunneling deep beneath the earth—without ever getting lost. For ...

Martin told me she would army crawl up to the turtles on the sand and dab around their eyes with a foam swab, soaking up the ...

This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the ...

Scientists have long puzzled over why Mars, once protected by a global magnetic field like Earth, now shows only a magnetic ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

"The Earth's magnetic field is not innocent or innocuous. Not only does it help birds migrate around the world, but can also be a positive force for human endeavors. "Our experiments in the ...

Researchers say they may have achieved Einstein's vision of a "unified field theory" that can unite two of nature's ...

Magnetic Force Microscopy (MFM) is a scanning probe microscopy technique ... MFM is based on the detection of magnetic interactions between a magnetized probe tip and the magnetic fields emanating ...

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 ...
