## What is the purpose of a magnetic compass?

A magnetic compass, which is used to assist in navigation, is an instrument that shows magnetic north. You must apply a correction to determine the direction of true north.

### What are the three uses of magnetic compass?

Answer

• to test the polarity in a magnet.
• to find the direction of magnetic field lines.
• to detect different directions.

#### What are the two uses of magnetic compass?

1) To detect the directions. 2) To check the polarity of other magnet and to plot magnetic field lines.

What is a magnetic compass used for and how does it work?

A compass works by detecting and responding to the Earth’s natural magnetic fields. The Earth has an iron core that is part liquid and part solid crystal, due to gravitational pressure. It is believed that movement in the liquid outer core is what produces the Earth’s magnetic field.

What are the disadvantages of magnetic compass?

The following characteristics of the magnetic compass limit its direction-finding ability: a) Sensitive to any magnetic disturbance. b) Useless at the magnetic poles and is sluggish and unreliable in areas near the poles. c) Deviation (explained later) changes as a ship’s magnetic properties change.

## What is the purpose of compass?

A compass is a device that indicates direction. It is one of the most important instruments for navigation. This compass was used by Robert Peary to reach the North Pole, allegedly the first person to do so. A compass is a device that indicates direction.

### What is the use of compass?

A compass is a navigational instrument for determining direction relative to the Earth’s magnetic poles. It consists of a magnetized pointer (usually marked on the North end) free to align itself with Earth’s magnetic field.

#### Where is compass used?

Function. Besides navigation, the compass is used in building and construction for marking landmarks and borders, and to measure horizontal lines and vertical lines for maps. The compass is a valuable tool used in the U.S. military, as well as in mining to assist in underground navigation.

What is the importance of magnetic compass in daily life?

The compass is used for navigation, location and direction. People use it to find their way, whether it is on a hiking trail or on a trip to a new location. It is an instrument composed of a suspended magnetic pointer that is attracted to the polarity of the North Pole.

What is a compass attracted to?

When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole.

## What happens when you put a magnet near a compass?

In Experiment 1, when you bring the compass near a strong bar magnet, the needle of the compass points in the direction of the south pole of the bar magnet. When you take the compass away from the bar magnet, it again points north.
