The needle in a compass is a small, magnetic needle that is suspended in a North-South direction in a compass. It is used to determine direction.
The needle in a compass is made of a small, magnetic needle that is suspended in a North-South direction in a compass. The needle is attached to a pivot so that it can rotate freely. The compass is a housing that holds the needle in place and has a orienting arrow that points in the direction of the North Pole.
The magnetic needle in a compass is attracted to the Earth’s magnetic North Pole. This is what causes the needle to rotate until it points in the direction of the North Pole. The direction of the North Pole can then be determined by following the orienting arrow on the compass.

Does the needle of a compass always point south?
The answer to this question is yes, the needle of a compass always points south. The reason for this is that the Earth’s magnetic field is constantly rotating, and the north end of the compass needle is attracted to the north end of the magnetic field.
Why does the needle of a compass point north?
When you’re out in the wilderness, lost and with no idea of where you are, your compass can be a life-saving tool. But have you ever stopped to wonder why the needle always points north?
The compass was invented in China over 2,000 years ago, and the first compasses pointed south. The design changed in Europe in the Middle Ages, when compasses began to be made with needles that pointed north.
So why does the needle in a compass always point north?
The Earth is surrounded by a magnetic field, which is created by the movement of the Earth’s molten core. This magnetic field creates a force that attracts the north end of a compass needle.
The Earth’s magnetic field is not uniform, and it changes over time. This means that the direction that a compass needle points can vary, depending on where you are in the world.
But overall, the force of the Earth’s magnetic field is strong enough that the needle in a compass will always point north.
How does a compass needle work?
A compass needle is a small, pointed piece of metal that is magnetized and used to indicate directions. It is attached to a compass, which is a device used to find directions. The compass needle points to the Earth’s magnetic North Pole, which is located near the geographic North Pole.
The compass needle is made of a magnetic material, such as iron, that is attracted to the Earth’s magnetic field. The Earth’s magnetic field is created by the movement of the Earth’s molten core. The compass needle is balanced on a pivot so that it can rotate freely. The compass housing holds the needle in place and also contains a magnet that interacts with the needle to create a magnetic force that points to the North Pole.
When you move the compass, the needle will rotate until it is aligned with the Earth’s magnetic field. The compass housing will then keep the needle in that position. The direction that the needle points is called the magnetic North Pole. The geographic North Pole is the point on the Earth’s surface that is closest to the North Pole.
How does a compass tell direction?
A compass is an instrument that is used to indicate the direction of magnetic north. The compass consists of a magnetic needle that is suspended in a fluid and a rotating housing that contains a graduated dial. The needle is attracted to the north pole of the Earth’s magnetic field, so it always points in the direction of magnetic north.
The graduated dial on a compass can be used to determine the cardinal directions (north, south, east, and west). To do this, you need to know the location of the compass’s orienting arrow. The orienting arrow is a small triangle that is located on the rotating housing of the compass. The orienting arrow always points to magnetic north.
To determine the cardinal directions, you need to first find the location of the sun. The sun is located in the sky at a particular angle at any given time of day. You can use a sundial to find this angle. Once you have found the sun’s location, you need to find the location of the compass’s orienting arrow. The orienting arrow is located on the rotating housing of the compass at the same angle as the sun.
Once you have found the location of the orienting arrow, you can use the graduated dial on the compass to find the cardinal directions. The cardinal directions are located at the points on the graduated dial that are aligned with the orienting arrow.

How does a compass needle work?
The earth’s magnetic field creates a force that can be detected by a compass. This force causes a compass needle to align itself with the earth’s magnetic field. The earth’s magnetic field is strongest near the poles, so the compass needle points towards the poles.
What is a compass needle made of?
A compass needle is a small, thin piece of metal that is magnetized and is used to indicate direction. It is attached to a compass and is used to determine the direction of magnetic north. The most common type of compass needle is made of steel, but there are also brass and aluminum needles available.
What are the parts of a compass?
A compass is a navigational instrument that is used to determine directions. It consists of a magnetic needle that is suspended in a liquid and points north. The compass has several parts that are important for its proper function.
The housing is the outer casing of the compass. It is typically made from plastic or metal and is designed to protect the inner components from damage. The base is the bottom of the housing and it houses the magnet that powers the compass. The dial is the top of the housing and it has a graduated scale that is used to measure angles. The bezel is the ring that surrounds the dial and it can be rotated to measure angles. The needle is the thin metal rod that is attached to the bezel. It is magnetized and points north. The pivot is the small post that the needle is attached to and it allows the needle to rotate. The fluid is a non-magnetic liquid that surrounds the needle and helps to keep it in place.
