The simplest explanation is that the needle aligns itself with the direction of the magnetic field lines. Since the lines are perpendicular to the direction of current, the needle will try to align that way also. It is only deflected west because Earth's magnetic field is still pulling the needle to point north. The needle will point along the ...
