A magneto‐optical effect theory based on the nonlinear Boltzmann equation is derived in the presence of a strong dc electric field. The addition of a phenomenological energy relaxation term to the Boltzmann equation provides analytical expressions for the magnetoconductivity in the limit of a quadratic deviation from Ohm's law. The current density is derived for a strongly degenerate electron gas, with an energy dependence of the momentum relaxation time. The Faraday rotation and ellipticity in a strong dc electric field are calculated.
