An ordinary compass indicates the direction of magnetic north, which is the direction a magnetic needle points due to the Earth's magnetic field. The needle is balanced on a pivot, allowing it to rotate freely and align itself with the magnetic field lines. This tool is commonly used for navigation and orientation, helping users determine their heading relative to the cardinal directions: north, east, south, and west.

How do you use an ordinary Compass?
To use an ordinary compass, hold it flat in your palm and make sure the needle can move freely. Rotate yourself and the compass until the needle points to the north direction marked on the compass. Now you can determine the other directions (east, west, south) based on the north reading.
What is the moveable bar in a compass called?
The movable bar in a compass is called the compass needle. It is typically a thin magnetized bar that aligns with the Earth's magnetic field to indicate direction.
Does a compass use electricity?
No, a traditional compass does not use electricity. It works based on the Earth's magnetic field to indicate directions.
What is ordinary suffixes?
Ordinary suffixes are suffixes that are commonly added to the end of words to modify their meaning or grammatical function. Examples include "-s" to indicate plural, "-ed" to indicate past tense, and "-ing" to indicate present participle.
How does a compass utilize magnetism to indicate direction?
A compass utilizes magnetism to indicate direction by aligning itself with the Earth's magnetic field. The needle inside the compass is a magnet that is free to rotate, and it points towards the Earth's magnetic north pole. This allows the compass to show the direction of north, south, east, and west based on the orientation of the needle.
How does a bar magnet interact with a compass?
A bar magnet interacts with a compass by aligning the compass needle along the magnetic field lines of the magnet. This causes the compass needle to point towards the North Pole of the magnet, allowing the compass to indicate the direction of the magnetic field.
What is the instrument called for telling direction?
A compass or a GPS system would do the trick. An altimeter will indicate whether you are maintaining, losing, or gaining altitude.
What does a dip compass do?
A compass does not point to the North Pole, it aligns itself with the lines of magnetic force at your location. In the Northern Hemisphere you are closer to the North Pole, so the strength from that direction is greater, and the compass "points north". In the Southern Hemisphere, similarly, the magnetic South Pole is closer, and the other end of the compass points to the south Pole. So far so good. But when you are close to either pole, the magnetic field dips into the earth - steeply at the Poles themselves. [Ordinary compasses are counterbalanced a little so the compass needle or card is approximately horizontal. The compass manufacturers divide the earth into five 'balance' zones.] So a dip compass is suspended between two pivots, and will indicate the steepness of the magnetic fields dip. It differs from an ordinary compass.
What is cardinal compass point?
Cardinal compass points are the four main points on a compass: north, south, east, and west. They are used to indicate directions on a map or in navigation.
A compass uses the property of to indicate direction.?
What property it uses depends on the type of compass. A magnetic compass uses magnetism. Some other compasses (which are more accurate) use the rotation of Earth itself.
What must be done first to an ordinary sewing needle to make it a compass needle?
To make an ordinary sewing needle into a compass needle, it must first be demagnetized by heating it to a high temperature and then allowing it to cool in a specific orientation. This aligns the needle's magnetic domains and makes it a more effective compass needle.
