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

The concept of magnetic field polarization is particularly relevant, as recent advances in optical technologies such as plasmonics 3,4,5,6, negative index metamaterials 7,8,9,10,11, ...

Researchers controlled the magnetic properties of a metal layer through the electrical polarization of a neighboring metal oxide layer. Computational simulations and experimental measurements ...

Earth's Magnetic Polarity Can Flip Much More Quickly Than Previously Thought. Published Aug 20, 2018 at 3:00 PM EDT Updated Aug 20, 2018 at 6:35 PM EDT. By . Katherine Hignett is a reporter based ...

NASA’s IXPE space observatory has examined the polarization of X-rays from the supernova wreckage Cassiopeia A to learn more about its powerful magnetic fields.

Scientists understand that Earth's magnetic field has flipped its polarity many times over the millennia. In other words, if you were alive about 800,000 years ago, and facing what we call north ...

Earth's magnetic field is not stable, and polarity reversals where the North and South poles flip has happened on average roughly every 200,000 years. During the past 180 years, Earth's magnetic ...

As we approach solar maximum, something strange is happening to the sun's magnetic field. We explore this flip in polarity in more detail and look at the effects it could have on Earth.

The poles of the sun’s magnetic field are fading away. But don’t panic: it’s all part of our host star’s usual 11-year cycle of activity.. Over the past couple of years, solar activity ...

Earth’s Magnetic Field Could Take Longer to Flip Than Previously Thought New research suggests a polarity reversal of the planet takes about 22,000 years, significantly longer than former estimates ...
