  The essence of the chiral magnetic effect is generation of an electric
current along an external magnetic field. Recently it has been studied by
Rebhan et al. within the Sakai--Sugimoto model, where it was shown to be zero.
As an alternative, we calculate the chiral magnetic effect in soft-wall AdS/QCD
and find a non-zero result with the natural boundary conditions. The mechanism
of the dynamical neutralization of the chiral chemical potential via the string
production is discussed in the dual two-form representation.
