As the iron and nickel inside our planet shift, so does Earth's magnetic field, meaning the North (and South) Poles are also ...

A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new ...

We encounter magnetic field sensors everywhere today – but few of us know it. These sensors make sure washing machines run concentrically, that headlights automatically adjust to the correct angle if ...

Earth is surrounded by a magnetic field generated by electric currents from within the planet. Compasses take advantage of this field to identify north and serve as a navigational aid. But one social ...

The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a magnet ...

In 2009, NASA's Chandra X-ray Observatory released a captivating image: a pulsar and its surrounding nebula that is shaped like a hand. Since then, astronomers have used Chandra and other telescopes ...

Think of it as the giant Koosh ball in the sky. A dazzling new image depicts the sun's many magnetic field lines, which snake all around Earth's star but are densest near sunspots. These darker and ...

Scientists have developed a way to produce models of where the magnetic field lines are several times each day. Here we have created a time-lapse version of these models over four days (2-3 each day) ...
