Researchers have identified a period of sluggish magnetic field flipping for planet Earth, some 40 million years ago – ...

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

Magnetic field reversal is a fascinating topic. You are brought up to think that the compass, pointing to the north, is an ...

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Earth's magnetic field dramatically flipped roughly 41,000 years ago. Now you can actually 'hear' this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

Add Yahoo as a preferred source to see more of our stories on Google. Earth's magnetic field is like an invisible shield that protects our planet from solar and cosmic radiation. While it might not be ...

Earth’s magnetic field and atmospheric oxygen appear to have moved in sync for half a billion years, pointing to a surprising connection between the planet’s deep interior and life-supporting ...

Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...

Just as the amplified magnetic field peaked, these electrons settled again, locking in the strong field’s direction. Benjamin Weiss, an MIT professor and study co-author, explains the process like ...
