Chiral magnetic effect is an interesting phenomenon that in principle occurs 
in heavy ion collision experiments. The intense magnetic field produced 
separates fermion charges and chiralities. This effect could be an evidence of 
nontrivial topological gluon configurations. There are many similarities 
between QCD in four dimensions and and QED in three dimensions. Here, I will 
show how it is possible to reproduce an equivalent effect in quantum 
electrodynamics confined into a plane.
