Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

A new theoretical study led by University of Delaware engineers reveals that magnons, a type of magnetic spin wave, can ...

Every new generation of eyes sees a new version of our galaxy, the Milky Way. This Impressionistic swirl of color represents the churning magnetic fields in giant dust clouds near the center of the ...

"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...

Multiferroics are materials that exhibit more than one ferroic property, typically ferroelectricity (i.e., a spontaneous electric polarization that can be reversed by electric fields) and ...

During geomagnetic disturbances, technology can experience malfunctions, particularly at higher latitudes. Common issues include: Disruptions in satellite systems and GPS navigation. Interference in ...

Our galaxy took shape more than 13 billion years ago, when clouds of cosmic dust collapsed from their own gravitational pull, and the resulting heat and pressure slowly transformed them into stars and ...

Massive stars, with their intense luminosities and rapid evolutionary cycles, present an intriguing laboratory for studying the role of magnetic fields in stellar dynamics. These stars often exhibit ...
