What does poles mean in physics?

The pole is the central point of the spherical mirror. The pole of the mirror is the point where the principal axis pierces the mirror. The letter P is commonly used to represent the pole. The principal axis is the straight line connecting the pole (P) and the center of curvature.

What do you mean by poles?

Definition of pole (Entry 3 of 4) 1 : either extremity of an axis of a sphere and especially of the earth’s axis. 2a : either of two related opposites. b : a point of guidance or attraction. 3a : either of the two terminals of an electric cell, battery, generator, or motor.

What is electric pole in physics?

pole, in electricity and magnetism, point where electric or magnetic force appears to be concentrated. A single electric charge located at a point is sometimes referred to as an electric monopole. An electric dipole consists of two equal and opposite charges separated by a distance.

What is a simple definition of magnetic poles?

magnetic pole, region at each end of a magnet where the external magnetic field is strongest. A bar magnet suspended in Earth’s magnetic field orients itself in a north–south direction. The north-seeking pole of such a magnet, or any similar pole, is called a north magnetic pole.

What is pole and Axis?

Pole of a mirror is the geometrical center of the spherical surface of the mirror. Principal axis is the straight line that joins the pole of the mirror to its center of curvature.

What is pole example?

A pole is defined as a long piece of wood, metal or other material. An example of a pole is what a United States flag hangs from in front of a fire department. noun. 1. The definition of a pole is either end of a dividing line through a sphere, or the opposing ends of two forces.

Why are the poles called poles?

These stem from Lechia, the ancient name for Poland, or from the tribal Lendians. Their names are equally derived from the Old Polish term lęda, meaning plain or field.

What are the 2 poles called?

Earth has two geographic poles: the North Pole and the South Pole. They are the places on Earth’s surface that Earth’s imaginary spin axis passes through. Our planet also has two magnetic poles: the North Magnetic Pole and the South Magnetic Pole.

What is the function of a pole?

In complex analysis (a branch of mathematics), a pole is a certain type of singularity of a function, nearby which the function behaves relatively regularly, in contrast to essential singularities, such as 0 for the logarithm function, and branch points, such as 0 for the complex square root function.

What is phase and pole?

An electric “pole” describes an electric charge determined by the number of protons and electrons in a given atom. An electric “phase” describes the rate at which the voltage in an alternating current oscillates.

What is the SI unit of electric pole?

Magnetic pole strength is the strength of a magnetic pole to attract magnetic materials towards itself . S.I. unit of magnetic pole strength is Ampere-meter (Am).

Where are magnet poles short answer?

Answer: Solution: Poles of a bar magnet are located at its two ends.

Where are the magnetic poles?

In 2009, while still situated within the Canadian Arctic at 84°54′N 131°00′W, it was moving toward Russia at between 55 and 60 km (34 and 37 mi) per year. As of 2021, the pole is projected to have moved beyond the Canadian Arctic to86.400°N 156.786°E. Its southern hemisphere counterpart is the south magnetic pole.

How many poles does a magnet?

Magnets have two poles, a north pole and a south pole. The magnetic field is represented by field lines that start at a magnet’s north pole and end at the south pole. When most people think of magnetism, they think about the magnetic force experienced between two magnets.

How many poles are there in earth?

1.3 > The northern and southern hemispheres of the Earth each have three poles – one geographic, one magnetic, and one geomagnetic.

What are the three types of poles?

They get their electricity from the substation. They can be divided into three types namely; Tangent distribution poles, guyed distribution poles, and self-supporting distribution poles. Tangent utility poles are the usual ones they are sequenced in a straight line with all other poles.

What is the pole and vertex?

The point at which 5 or more edges meet at a vertex is referred to as a pole. Most commonly poles are seen at the tips of sphere primitives or segmented cylinder caps.

What are the poles answer?

pole are the southernmost and northwest areas and having cold weather ….

What is simple pole give example?

Example 8.9. f(z)=z+1z=1+1z. Thus, z=0 is a pole of order 1, i.e. a simple pole.

What is pole class9?

Pole:The geometric centre of the spherical surface of mirror is called the pole of mirror. Principal axis:It is the straight line joining the pole of the mirror to its centre of curvature.

Which poles are magnets?

The north pole and south pole are the two poles of a magnet.

What is single pole and two pole?

Both single pole and double pole switches can be either single or double throw. A pole refers to the number of separate circuits a switch can control, a single pole switch can operate one circuit whereas a double pole switch can control two circuits. A throw refers to how many positions can be activated by a switch.

Do all magnets have poles?

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

Why do magnetic poles attract?

Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).

What are magnets 2 poles called?

The end that faces the north is called the north-seeking pole, or north pole, of the magnet. The other end is called the south pole. When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges.
