A new analysis of computer simulations of Earth’s magnetic field suggests that its behavior was different early in Earth’s history, resulting in greater stability and fewer reversals of the magnetic ...

We know magnetism as a fundamental force of nature that plays a crucial role in both the natural world and modern technology. It governs the behavior of materials at the atomic level and is essential ...

I just got back from a trip to Japan. While there I met with several people involved in public policy in Tokyo, visited my professor who advised me for my PhD at Shinshu University in Nagano Japan (Dr ...

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry "spintronic" memory chips. The new magnetic state is a mash-up ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

In 2008, Erez Ben-Yosef unearthed a piece of Iron Age "trash" and inadvertently revealed the strongest magnetic-field anomaly ever found. Ben-Yosef, an archaeologist at Tel Aviv University, had been ...

The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...

Although the magnetic field of Mars hasn't been in effect for billions of years, the evidence it left behind may suggest that the planet's core is entirely liquid. Magnetic imprints still exist on ...

Libor Šmejkal has a fondness for the artwork of M. C. Escher, whose work was often inspired by mathematics. One of Šmejkal’s favourite pieces is Horseman, a striking picture that features an elaborate ...

The original version of this story appeared in Quanta Magazine. Our planet is doomed. In a few billion years, the sun will exhaust its hydrogen fuel and swell into a red giant—a star so big it will ...
