The flow is exposed to a uniform magnetic field which is oriented perpendicular to two duct walls and aligned with the non-conducting cylinder.
In most cases the channel margins are not seen, but they can be shown to be several hundred metres wide, perpendicular to palaeoflow.
The incoming wave fronts are perpendicular to the major axis.
In a steady-state monoclinic flow this section is perpendicular to the rotation axis of rigid objects.
A spherical mirror collects and focuses the light onto the target spot perpendicular to the horizontal mounting plate.
The electric field must always be perpendicular to the surface of a conductor.
The waves are transverse, which means that the direction of oscillation has to be perpendicular to the direction of motion of the wave.
The polariser is measuring polarisation perpendicular to the optical axis.
