  The effect of the random magnetic field distribution on the phase diagrams
and ground state magnetizations of the Ising nanowire is investigated with
effective field theory with correlations. Trimodal distribution chosen as a
random magnetic field distribution. The variation of the phase diagrams with
that distribution parameters obtained and some interesting results found such
as reentrant behavior. Also for the trimodal distribution, ground state
magnetizations for different distribution parameters determined which can be
regarded as separate partially ordered phases of the system.
