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 ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies ...

One way to get moving charges is to run electric current through a wire. (This is literally a stream of electrons.) This will create a magnetic field, and other wires with electric current will ...

Magnetic fields are everywhere in the universe ... dust grains would create a weak-but-wide-scale electrical current, like a copper wire 1,000 light-years across. Because the filtering of ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

With today’s data rates of only a few hundred megabytes per second, access to digital information remains relatively slow. Initial experiments have already shown a promising new strategy: Magnetic ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

One promising solution comes from an unusual effect called nonreciprocal electronic transport, where electric current ... the magnetic structure using external magnetic fields, which in turn ...

Indeed there is, in addition to the obvious ways to manipulate the spin using magnetic fields, an indirect effect on the electron spin from externally applied electric fields, due to the so-called ...
