Angular momentum is a fundamental quantity in physics that describes the rotational motion of objects. In quantum physics, it ...

A rare geological event occurs every 300,000 years or so: the Earth’s magnetic poles flip. The magnetic poles are the two ...

Beneath the bogs of New Zealand’s Northland is a massive Ngāwhā kauri, living from 41,000 to 42,500 years ago, which gives an isolated, unbroken record of a period when Earth’s magnetic field declined ...

The sun is on the verge of a significant event: a magnetic field reversal. This phenomenon happens roughly every 11 years and marks an important stage in the solar cycle. The shift in polarity ...

Our magnetic field provides some protection from the onslaught of particles from the solar wind and cosmic rays from deep space. During a pole reversal, the field weakens, although it doesn’t ...

The last true sustained reversal of the magnetic poles happened around 780,000 years ago, and is named the Brunhes–Matuyama reversal after the geophysicists who first found evidence for it.

Scientists convert Earth's magnetic field collapse from 41,000 years ago into chilling audio, revealing ancient cosmic ...

BBC Sky at Night Magazine, "Scientists discover how a reversal of Earth's magnetic field could affect our climate," Jan. 4, 2023. PolitiFact, ...

NASA has detected a mysterious weakening in Earth’s magnetic field over South America, here’s what it means for satellites and our planet.

The reversal could actually have a beneficial effect on Earth. The sun is on the verge of a significant event: a magnetic field reversal. The sun undergoes such a reversal every 11 years, which ...
