摘要：

We study the effects of a uniform magnetic field on the evolution of cosmological perturbations, in a full relativistic framework, considering the effects of anisotropies. We take advantage of the synchronous gauge to simplify the equations. We study both super-horizon scales in radiation dominated universe and sub-horizon scales in both a full relativistic framework and the Newtonian limit in case of adiabatic sound speed.
