>Hello Sohib EditorOnline, in this article, we will discuss cara kerja kompas (how a compass works). A compass is a navigational instrument that has been used for centuries to determine direction, and its basic principles remain the same today. Let’s dive into the inner workings of a compass and learn how it operates.

What is a Compass?

A compass is a simple navigational tool that helps determine directions. It consists of a magnetized needle that can rotate freely on a pivot point, and it is enclosed in a circular or rectangular case that is usually marked with the cardinal points of north, east, south, and west. The needle always points towards the magnetic north pole of the Earth, which is different from the geographic north pole.

Compasses are used in many applications, including navigation, surveying, map-making, and even in everyday life, such as camping and hiking.

Cara Kerja Kompas: How a Compass Works

Magnetic Fields

The principle behind how a compass works is based on Earth’s magnetic fields. The Earth has a magnetic field that is generated by its core, and this magnetic field causes the needle of the compass to align with it. The needle is magnetized, and when it is placed on a pivot point, it will rotate and align itself with the magnetic field of the Earth.

The magnetic field of the Earth is generated by the movement of molten iron in the Earth’s core. As the molten iron moves, it generates a magnetic field that extends outwards from the Earth’s core and into space. This magnetic field is what affects the needle of the compass and causes it to align with it.

Magnetic Declination

One important thing to note is that the magnetic north pole is not the same as the geographic north pole. The magnetic north pole is the point on the Earth’s surface where the magnetic field points directly downwards. This point is constantly moving, and it is currently located in the Arctic Ocean, near the Canadian coast.

The difference between the magnetic north pole and the geographic north pole is known as magnetic declination. Depending on where you are in the world, magnetic declination can vary, and it is important to know how to account for it when using a compass for navigation.

Compass Components

Now that we know how a compass works, let’s take a closer look at its components. A typical compass consists of the following parts:

Component Description
Needle A magnetized needle that can rotate freely on a pivot point.
Pivot Point A point around which the needle rotates.
Cardinal Points The markings on the compass that indicate the four cardinal points of north, east, south, and west.
Housing The case that encloses the needle and markings.
Lid A protective cover that can be placed over the compass to prevent damage.

Using a Compass

Now that we know how a compass works and its components, let’s learn how to use it. Here are the basic steps:

  1. Hold the compass level in your hand, making sure that the needle is not touching anything.
  2. Rotate the housing until the North marking on the compass is aligned with the needle.
  3. The direction that the South marking is pointing towards is south; the direction the East marking is pointing towards is east, and the direction the West marking is pointing towards is west.
  4. In order to account for magnetic declination, you will need to adjust your compass. This adjustment will vary depending on your location and can usually be found on a map or with a GPS device. Once you know the magnetic declination for your area, you can adjust your compass accordingly.
  5. When navigating, make sure to keep your compass level and away from any metal objects, as these can interfere with the magnetic field and affect the accuracy of your compass.

Final Thoughts

A compass is a simple yet effective navigational tool that has been used for centuries. Understanding how it works and how to use it properly can add an extra layer of safety and accuracy to outdoor activities such as hiking, camping, and hunting. We hope this article has provided you with a better understanding of cara kerja kompas and its importance in navigation.

FAQ

What is the difference between true north and magnetic north?

True north is the direction towards the geographic North Pole, while magnetic north is the direction towards the magnetic North Pole. The two directions differ because the magnetic North Pole is not located at the same point as the geographic North Pole.

Can a compass be affected by other magnetic fields?

Yes, a compass can be affected by other magnetic fields, such as those generated by metal objects, power lines, or electronic devices. To ensure accuracy, it is important to keep your compass away from these sources of interference.

What is the purpose of the housing on a compass?

The housing on a compass is designed to protect the needle and markings from damage and to help stabilize the needle and pivot point. It is also useful for taking bearings and for sighting objects when using the compass for navigation.

What is declination adjustment?

Declination adjustment is the process of adjusting your compass to account for the difference between true north and magnetic north in your area. This adjustment can vary depending on your location and can usually be found on a map or with a GPS device.
