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

Earth’s magnetic field has flipped about 170 times in the last 100 m years, and the next reversal is not a matter of if but ...

Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature.

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

When the sun reaches its period of peak activity, known as solar maximum, our star's magentic field will suddenly reverse. But why does it happen, and will it impact Earth? When you purchase through ...

Earth’s magnetic field feels steady and dependable, but over geological time it is anything but fixed. The magnetic north and south poles have swapped places many times in the planet’s history in ...

Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it encompasses both the intrinsic spin of particles and their orbital motion ...
