Abstract
We compute the Chiral Magnetic Effect (CME) in a cylindrical region coaxial with the external magnetic field. As the boundary condition we require vanishing of the radial component of the electric current on the cylinder side wall. We find that when the magnetic length is comparable or larger than the cylinder radius, the CME is suppressed compared to the corresponding result in infinite medium. As a result, for a given cylinder radius, the suppression is stronger in weak fields. We argue that the electric current generated by the CME vanishes at the cylinder wall and monotonically increases towards the symmetry axis.
