Magnetic fields thread through galaxy clusters and stretch along cosmic filaments spanning hundreds of millions of light-years. They deflect cosmic rays, shape star formation, and influence the ...

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 ...

How does the Earth generate its magnetic field? While the basic mechanisms seem to be understood, many details remain unresolved. A team of researchers from the Center for Advanced Systems ...

Kinetic simulations distinguish collective from diffusive charge and heat transport in a graphene Corbino disk.

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the solar wind, high-energy particle transport, and galaxy formation. Small-scale ...

A Superconducting Quantum Interference Device (SQUID) is an ultrasensitive superconducting sensor used to measure extremely small changes in magnetic flux. It consists of a superconducting loop ...
