Examples of pole in the following topics:
-
- All magnets have two poles, one called the north pole and one called the south pole .
- North and south poles always exist in pairs (there are no magnetic monopoles in nature), so if one were to split a permanent magnet in half, two smaller magnets would be created, each with a north pole and south pole.
- The iron becomes a permanent magnet with the poles aligned as shown: its south pole is adjacent to the north pole of the original magnet, and its north pole is adjacent to the south pole of the original magnet.
- North and south poles always occur in pairs.
- Attempts to separate them result in more pairs of poles.
-
- Another visual illusion is the barber pole illusion.
- In the barber pole illusion, a barber pole is rotated along the x-axis, but the diagonal stripes appear to move along the pole in a vertical fashion (y-axis) that is inconsistent with the actual direction the pole is turning in.
- The barber pole illusion also demonstrates how motion is perceived through first-order perception, which only sees movement as continual.
- In the barber pole illusion, a barber pole is rotated along the x-axis, but the diagonal stripes appear to move down the pole's y-axis in a way that is inconsistent with the actual direction the pole is turning in.

- The most famous examples include Totem poles, Transformation masks, and canoes.
- Totem poles are monumental sculptures carved on poles, posts, or pillars with symbols or figures made from large trees (mostly western red cedar) by indigenous peoples of the Pacific Northwest coast.
- Totem pole carvings were likely preceded by a long history of decorative carving, with stylistic features borrowed from smaller prototypes.
- United States governmental policies and practices of acculturation and assimilation sharply reduced totem pole production by the end of 19th century.
- Renewed interest from tourists, collectors, and scholars in the 1880s and 1890s helped document and collect the remaining totem poles, but nearly all totem pole making had ceased by 1901.

- Asmat art consists of elaborate stylized wood carvings, such as the bisj pole, that are designed to honor ancestors.
- Carved out of a single piece of a wild nutmeg tree, bisj poles can reach heights of up to 25 feet.
- Many rituals involved the bisj poles, including dancing, masquerading, singing, and headhunting—all performed by men.
- Bisj poles often had a receptacle at the base that was meant to hold the heads of enemies taken on headhunting missions.
- Although the practice of headhunting ended in the Asmat region in the 1970s, the poles are still used in rituals today.
-
- The polar grid is represented as a series of concentric circles radiating out from the pole, or the origin of the coordinate plane.
- The reference point (analogous to the origin of a Cartesian system) is called the pole, and the ray from the pole in the reference direction is the polar axis.
- The first coordinate $r$ is the radius or length of the directed line segment from the pole.
- Moreover, the pole itself can be expressed as ($0, ϕ$) for any angle $ϕ$.
- Points in the polar coordinate system with pole $0$ and polar axis $L$.
-
- It is a genus comprising elongated forms with clusters of flagellae at both poles.
- One daughter is a mobile "swarmer" cell that has a single flagellum at one cell pole that provides swimming motility for chemotaxis.
- The other daughter, called the "stalked" cell, has a tubular stalk structure protruding from one pole that has an adhesive holdfast material on its end, with which the stalked cell can adhere to surfaces.

- Imagine the axis of rotation as a pole through the center of a wheel.
- The pole protrudes on both sides of the wheel and, depending on which side you're looking at, the wheel is turning either clockwise or counterclockwise.
- From a spinning disc, for example, let's again imagine a pole through the center of the disc, at the axis of rotation.
- Using the right hand rule, your right hand would be grasping the pole so that your four fingers (index, middle, ring, and pinky) are following the direction of rotation.
- In addition, your thumb is pointing straight out in the axis, perpendicular to your other fingers (or parallel to the 'pole' at the axis of rotation).
-
- Since cleavage is impeded by the vegetal pole, there is a very uneven distribution and size of cells.
- Cells are more numerous and smaller at the animal pole of the zygote than at the vegetal pole.
- The inner cell mass remains in contact with the trophoblast, however, at one pole of the ovum.
- This is named the embryonic pole, since it indicates the location where the future embryo will develop.
-
- that has poles at $z= \ldots, -2, -1, 0, 1, 2 \ldots$ and for large values of $z$$f(z)$ quickly approaches zero, so the integral
- The sum of the integrals about all of the poles must vanish.
- ~\ref{fig:polesfz} shows all of the poles.
- At the poles (solid points in the figure) other than at the origin, the function is given by
- where $C_R$$R$ is a circle of radius $R$ centered on the pole.
-
- A small compass placed in these fields will align itself parallel to the field line at its location, with its north pole pointing in the direction of B.
- They go from the north pole to the south pole.
- The last property is related to the fact that the north and south poles cannot be separated.
- (A) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet (recall that Earth's north magnetic pole is really a south pole in terms of definitions of poles on a bar magnet. ) (B) Connecting the arrows gives continuous magnetic field lines.
