In optics, the inverse Faraday effect is the effect opposite to the Faraday effect. A static magnetization <math>\mathbf{M}(0)</math> is induced by an external oscillating electrical field with the frequency <math>\omega</math>, which can be achieved with a high intensity laser pulse for example. The induced magnetization is proportional to the vector product of <math>\mathbf{E}</math> and <math>\mathbf{E}^*</math>:

<math>\mathbf{M}(0)\propto[\mathbf{E}(\omega)\times\mathbf{E}^*(\omega)]</math>

From this equation we see that the circularly polarized light with the frequency <math>\omega</math> should induce a magnetization along the wave vector <math>\mathbf{k}</math>. Because <math>\mathbf{E}</math> 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.
