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.

Now we have a more accurate map of magnetic north, one that should be good for another half a decade. For the first time, a higher resolution map is also available, which offers more than 10 times ...

Over the past few decades, magnetic north’s movement has been ... of approximately 2,051 miles (3,300 kilometers) at the equator, and the first high-resolution model, with spatial resolution ...

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 strength of the Earth’s magnetic field ranges between 25,000 and 65,000 nano-Tesla (nT) with values of 31-58,000 nT between the equator and 50 degrees latitude.
