its because it only allows current to passy through one direction. They are like diodes
It (1) provides a means of connecting a rotating coil to the external circuit, and (2) it is a rotating switch which ensures that the direction of the current through the coil always acts in the same direction relative to the magnetic field in order to ensure its torque acts in the same direction.
In that case, the magnetic field caused by the current would also be reversed. As for the wire itself, it would feel a force in the opposite direction, due to the interaction of the magnetic fields.
A filter drier for a cooling only condensing unit will have an arrow pointing in one direction. This is because the refrigerant that passes through it will always flow in the same direction. A heat pump filter drier must have the ability to allow the refrigerant to flow through it in either direction and so a filter drier that is made for a heat pump will have two arrows pointing in opposite directions.
the back emf increases so that high currents doesn't pass through the field windings
They are not getting blood through because of the certain position there in.
The clutch on a 2155 can be adjusted through the linkage. By loosening and shifting it in one direction, the position of the clutch and its tension can be changed.
The light or image is focused at a different position relative to the real position of the emitting light. This is dependent on the type of lens.

It'll take off at what to it appears as the easiest direction.
It is spread out into a spectrum, then recombined into white light.
in the direction of through to, toward, withinin the direction of through to, toward, within
Relationship or position in space: Prepositions are used to show the relationship or position of one object to another. Examples include "on," "in," "at," "under," and "beside." Time: Prepositions are used to indicate time, such as "during," "before," "after," and "since." Direction: Prepositions indicate direction, like "towards," "into," "out of," and "through." Cause or reason: Prepositions can indicate cause or reason, such as "because of," "due to," "for," and "with." Possession: Prepositions indicate possession, like "of," "to," and "from."
The definition for the word parallax is "the effect whereby the position or direction of an object appears to differ when viewed from different positions, e.g., through the viewfinder and the lens of a camera."
in an adjacent coils ,the current flows in same direction so there is force of attraction shortening the coils.
Because the sun moves through the sky, or at least it appears to do that. Since the sun's position changes with respect to objects on the earth so do their shadows.
