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.

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 ...

Save guides, add subjects and pick up where you left off with your BBC account. An electric current can be induced in in a coil of wire by moving a magnet in and out of the coil. AC generators are ...

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 ...

“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.
