  We investigate the effects that a tilting of the magnetic field from the
parallel direction has on the states of a 1D Majorana nanowire. Particularly,
we focus on the conditions for the existence of Majorana zero modes, uncovering
an analytical relation (the sine rule) between the field orientation relative
to the wire, its magnitude and the superconducting parameter of the material.
The study is then extended to junctions of nanowires, treated as magnetically
inhomogeneous straight nanowires composed of two homogeneous arms. It is shown
that their spectrum can be explained in terms of the spectra of two independent
arms. Finally, we investigate how the localization of the Majorana mode is
transferred from the magnetic interface at the corner of the junction to the
end of the nanowire when increasing the arm length.
