There are several theories about how the Earth and the Moon were formed, most involving a giant impact. They vary from a model where the impacting object strikes the newly formed Earth a glancing blow ...

Magnetic signatures hidden inside rocks tell us a lot about Earth's magnetic field and the way continents and tectonic plates have shifted across millennia – but for some periods, the geological ...

This video explains what magnets are and how magnetic fields are generated through the alignment of atomic structures. Magnets influence electric currents, force interactions, and are used in many ...

Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory ...

A team of scientists from the University of Liverpool have found two strange anomalies that have affected the Earth's ...

(Nanowerk News) MIT physicists have created a new ultrathin, two-dimensional material with unusual magnetic properties that initially surprised the researchers before they went on to solve the ...

Skyrmions, in which electron spins inside a magnet are arranged like vortices, are a key structure in next-generation ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

People have warned for years that magnets can wipe out hard drives, but the real answer is a lot less dramatic than that old ...

Add Yahoo as a preferred source to see more of our stories on Google. One of the most peculiar things about Uranus and Neptune is their magnetic fields. Each of these planets has a hot mess of a ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...
