Rapid shifts in the Earth’s north magnetic pole are forcing researchers to make an unprecedented early update to a model that helps navigation by ships, planes and submarines in the Arctic, scientists said.
Scientists are using clues from ancient artifacts to help them predict the future of the magnetic field, but the original prediction is way overdue.
The Earth is blanketed by a magnetic field. It’s what makes compasses point north, and protects our atmosphere from continual bombardment from space by charged particles such as protons.
Earth’s magnetic field hasn’t gone through a reversal when predicted. It could be within the next 2000 years, but it could happen at any moment.
