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

As sunspots emerge on the sun's surface close to its equator, their orientations will match the old magnetic field, while sunspots forming closer to the poles will have a magnetic field matching the ...

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

The Earth’s magnetic north pole has been slowly inching its way across the Arctic for decades, but recently, its path […] The ...

Scientists released an update to a model that maps the ever-moving pole and has significant implications for navigation ...

"The current behavior of magnetic north is something that we have never observed before." For decades, scientists have been tracking the shift in Earth's magnetic north pole away from Canada and ...

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 ...

The Little Bee B1 is an open source magnetic field and current probe based on an Anisotropic Magneto-Resistive (AMR) magnetic sensor. It directly senses magnetic fields and measures current with a ...

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.

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 ...
