400 years of discussion and we’re still not sure what creates the Earth’s magnetic field, and thus the magnetosphere, despite the importance of the latter as the only buffer between us and ...

Every so often, Earth's magnetic poles completely flip. What causes this to happen? And how do these reversals affect life on Earth?

Earth’s magnetic North Pole is shifting from Canada to Siberia due to changes in the flow of molten iron and nickel in the outer core. This movement has accelerated in recent years, impacting ...

Earth's magnetic field does not align perfectly with the axis of rotation, ... A 17,000 yr paleomagnetic secular variation record from the southeast Alaskan margin: ...

But relax and don’t worry about the Earth tumbling ass over teakettle and don’t toss out your compass, because the farther you navigate from the magnetic North Pole, the smaller the variation between ...

Extending from Earth like invisible spaghetti is the planet's magnetic field. Created by the churn of Earth's core, this field is important for everyday life: It shields the planet from solar ...

Planet Earth 150,000-year history of Earth's magnetic field reveals clues about the climate when early humans were spreading out of Africa The Sun A mysterious, 100-year solar cycle may have just ...

Earth's magnetic field changes from day to day, hour to hour. "In Australia, the Earth's field is typically about 50,000 nanoteslas. There's maybe a 15 nanotesla variation through what we call a ...

A huge and unusually weak point in Earth's magnetic field may have existed for at least 11 million years, scientists have said. By studying volcanic rocks, researchers have gained a better ...

Earth's magnets. The Earth has an iron core, and movement within its outer part is likely responsible for sustaining a magnetic field, which constitutes much of what we measure at the Earth's surface.

Scientists have discovered that the 'weak spot' in Earth's magnetic field is growing, allowing harmful radiation to come closer to our planet's surface. The region, known as the South Atlantic ...
