What is a magnetic needle?
A magnetic needle is a small magnetized object, often shaped like a pointer, that aligns itself with Earth's magnetic field when freely suspended. It is commonly used in compasses to indicate geographic directions, with one end pointing towards the magnetic north. The needle's orientation helps navigators determine their heading relative to the Earth's magnetic poles.
What is a magnetic compass?
A magnetic compass has a needle mounted in a way that allows it to turn freely. Tis needle always lines up with Earth's magnetic field and points toward magnetic north. The needle is set over a diagram that shows east,south, and west. By knowing which way is north, a sailor can find the other diections.

A device that has a magnetized needle that spins freely?
The device you are describing sounds like a compass. The magnetized needle aligns with the magnetic field of the Earth, allowing users to determine their direction relative to the north.
Why does stroking a needle with a magnet make it magnetic?
Stroking a needle with a magnet aligns the magnetic domains in the needle material in the same direction, causing the needle to become magnetized. This alignment of domains creates a magnetic field in the needle, giving it magnetic properties.
What is a magnetized needle that is attracted to the Earth's North magnetic pole?
It is still a needle, but could be referred to as a compass needle.
What can be used for a compass?
a freely suspended magnetic needle as it will always point to the north - south direction
What is an instrument for determining direction consisting essentially of a freely suspended magnetic needle that points toward the magnetic north?
This is the description of a magnetic compass.
What is a compass?
A compass is an instrument for determining direction consisting essentially of a freely suspended magnetic needle that points toward the magnetic north.
What is a device that has a magnetized needle that can spin freely?
A compass has a magnetized needle that can spin freely.
How does a compass needle align itself?
A compass has a needle that is magnetized. This needle is suspended so that it can rotate freely and it can align itself with any magnetic field it is exposed to.If you put a magnet close to a compass, the needle will align itself with the magnets magnetic field.It picks up the earth's magnetic field.answer 2 A magnetic compass needle aligns itself with the lines of magnetic force at your locality.It picks up the earth's magnetic field.answer 2 A magnetic compass needle aligns itself with the lines of magnetic force at your locality.
What is magnetic meridian in compass surveying?
The magnetic meridian in compass surveying is the line passing through a compass needle when it is freely suspended and allowed to align with the Earth's magnetic field. It represents the direction of the magnetic north pole at a particular location on the Earth's surface. It is an important reference in compass surveying for determining directions.
How does a compass work off of magnetism?
There is a magnetic field surrounding the Earth. The positive pole of this magnetic field (called the north magnetic pole) is near the North Pole. A compass has a freely rotating needle that is magnetized such that one end of the needle points toward the north magnetic pole.
In the first crude compass why was the needle floated in water?
The needle was floated in water in the first crude compass to reduce friction and allow it to move freely in response to Earth's magnetic field. This helped the needle align itself with the Earth's magnetic north and south poles, indicating direction.
What will happen if you place a small compass in a magnetic field?
When a small compass is placed in a magnetic field, the needle of the compass will align itself with the direction of the magnetic field. This is because the needle is magnetized and responds to the magnetic forces in the surrounding area.

How does a needle on a compass align itself?
A needle on a compass aligns itself with the Earth's magnetic field. The needle is magnetized, with one end pointing towards the Earth's magnetic north pole and the other end pointing towards the magnetic south pole. This alignment allows the needle to point in the direction of magnetic north.
What would happen is you rubbed a needle back and forth on a magnet?
Rubbing a needle back and forth on a magnet would align the magnetic domains within the needle, causing it to become magnetized. The needle would then exhibit magnetic properties and attract items such as paper clips or iron filings.
