Your navigation system just got a critical update, one that happens periodically because Earth’s magnetic north pole keeps ...

It's time to recalibrate the navigation systems on ships, airplanes, as the position of the magnetic North Pole is officially ...

For decades, Earth’s magnetic north pole has been slowly drifting across the Arctic, but recent shifts in its path have caught the attention of scientists—and those who rely on precise navigation ...

As we approach solar maximum, something strange is happening to the sun's magnetic field. We explore this flip in polarity in ...

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused by ...

Passive maglev uses permanent magnets in a specific configuration to create a constant magnetic current that levitates the pod, similar to the magnets you might've played with as a kid.

“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 ...

Current estimates predict solar maximum will ... known as the Hale cycle. This magnetic cycle lasts approximately 22 years, through which the sun's magnetic field reverses and then reverts to ...
