Over the past centuries, Earth's magnetic north has been drifting east at an accelerating pace, shifting thousands of kilometers across the globe. The massive, compass-wobbling trend is being driven by vast oceans of liquid metal in Earth’s interior and some fundamental principles of electromagnetism.

Scientists tracking Earth's wandering magnetic pole have spotted it heading from Canada toward Siberia in recent years. Where it will end up, no one knows.

The magnetic North Pole is the direction that a compass needle points, and it is not a fixed location; it changes due to magnetic activity beneath the Earth's crust.
