The World Magnetic Model predicts the difference between magnetic north and true north at every point on Earth .
It plays an integral role in satellite and aircraft navigation and helps smartphone users orient themselves using services like Google Maps .
A new version of the model is released every five years to account for changes in the magnetic field.
For most people, the 2025 update won't result in any noticeable changes to navigation.

"We keep the updates coming so that it's only a bit of time, small enough that most people don't notice," he says.
