This article reviews the fundamentals, phenomena, devices and materials of spin-transfer torques, at the heart of this rapidly advancing field of current-induced magnetization dynamics.

Northern Lights may appear in the D.C. area and Colorado due to a G4 solar storm, with possible power and communication ...

Lead author Dr Denny Oliveira, of Nasa’s Goddard Space Flight Centre, Maryland, said: ‘Auroras and geomagnetically induced currents are caused by similar space weather drivers. ‘The aurora ...

The induced voltage produces an induced current if the conductor is connected in a complete circuit. As with all currents, the induced current creates a magnetic field around itself. Note that ...

“Auroras and geomagnetically induced currents are caused by similar space weather drivers,” explained Dr Denny Oliveira of NASA’s Goddard Space Flight Center, lead author of the article.

Geomagnetic storms generate induced currents, which flow through the electrical grid. The geomagnetically induced currents, which can be in excess of 100 amperes, flow into the electrical ...

Eddy currents, also called Foucault current, are loops of electrical current induced within a conductor by a time-varying magnetic field in that conductor (Figure 1). This phenomenon of induction was ...

Grid operator PJM Interconnection has issued a geomagnetic disturbance (GMD) warning after observing “persistent geomagnetically induced current (GIC) at multiple stations” late on Friday.
