  Using AdS/CFT correspondence we study non-equilibrium phase transition in the
presence of a constant external magnetic field. The transition occurs when the
sign of differential conductivity reverses. Utilizing numerical method we show
that the type of transition depends on the value of magnetic field as well as
the temperature of gauge theory. Moreover we show that this transition does not
depend on the supersymmetry and the subspace on which the fundamental matter
fields live.
