Inverse Faraday effect
Encyclopedia
The inverse Faraday effect is the effect opposite to the Faraday effect
. A static magnetization
is induced by an external oscillating electrical field with the frequency 
, which can be achieved with a high intensity laser
pulse for example. The induced magnetization is proportional to the vector product of
and 
:
From this equation we see that the circularly polarized light with the frequency
should induce a magnetization along the wave vector
. Because 
is in the vector product, left- and right-handed polarization waves should induce magnetization of opposite signs.
The induced magnetization is comparable to the saturated magnetization of the media.

In physics, a wave vector is a vector which helps describe a wave. Like any vector, it has a magnitude and direction, both of which are important: Its magnitude is either the wavenumber or angular wavenumber of the wave , and its direction is ordinarily the direction of wave propagation In...
