  We present a microscopic calculation of the inverse Faraday effect in metals.
We derive a static local magnetic moment induced on the application of
high-frequency light, using the Eilenberger formulation of quasiclassical
theory. We include the effect of disorder and formulate a theory applicable
across the entire temperature range, in the absence of external applied fields.
For light-induced electric fields of amplitude $\sim 100 kV/cm$, the induced
fields are large, $\sim 0.1 T$ for metallic Nb! The predictions of our theory
agree with recent experimental and theoretical results [1]. An extension of
this approach to superconductors would open a new route of inducing orbital
magnetic field and potentially vortices in superconductors.
