And all these little dust grains have little magnetic fields associated with them, because all the grains are made of electric charges and they're spinning around themselves. When light from ...

NASA's EZIE (Electrojet Zeeman Imaging Explorer) mission has taken its first measurements.

When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

“The electric and magnetic fields at a material’s atomic level determine its bulk properties and behavior, and are an essential area of research,” says Toshiaki Tanigaki, a senior researcher ...

Researchers say they may have achieved Einstein's vision of a "unified field theory" that can unite two of nature's ...

How a tokamak works: The electric field induced by a transformer drives a current (big red arrows) through the plasma column. This generates a poloidal magnetic field that bends the plasma current ...
