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 ...

Solve a rotating-coil electromagnetism problem by deriving the induced emf from changing magnetic flux. Learn how coil area, number of turns, rotation rate, and magnetic field strength set the emf ...

A Simon Fraser University cosmologist believes his team's new research may bring them a step closer to cracking one of science's biggest questions—the Hubble tension. The quest to determine how fast ...

At a Thursday lecture event, Benjamin Weiss, a professor of Earth and planetary sciences at the Massachusetts Institute of Technology, spoke about his recent research on the lunar dynamo, which ...

A major dip in the Earth’s magnetic field over the South Atlantic has been puzzling scientists for over a century. An international team of researchers analyzed data collected by the European Space ...

After signing him in March, Aaron Glenn said the Jets were going to let Justin Fields “play quarterback.” Through six weeks, it is time to cut the Fields experiment short. On Sunday, the Jets lost to ...

If our planet flips and no one’s around to hear it, does it still make a sound? Scientists have managed to put a chilling soundtrack to the flipping of Earth’s magnetic field — and the result is ...

One of the big beauties of field watches is their simplicity. Sure, there have been some positively opulent examples over the years. But true field watches — at least ones fit for their original ...

This pen truly is mightier than the sword. A team of researchers at UCLA has developed a high-tech diagnostic pen that can detect signs of Parkinson’s disease with over 96% accuracy, offering a ...
