The needles of compasses are typically made from magnetic materials such as steel or iron. These materials can be magnetized and align with the Earth's magnetic field, allowing the compass to point in the direction of magnetic north.
The main materials used to make a magnetic compass are a magnetized needle, usually made of steel or iron, and a housing or casing to protect the needle. The casing may be made of materials like plastic, glass, or metal. Additionally, some compasses have a fluid-filled chamber to dampen the movement of the needle and improve accuracy.
Compass needles are typically made from magnetized materials such as iron or steel. These materials are able to become magnetized and align with the Earth's magnetic field, allowing the compass needle to point north.
An electric current can be used to deflect a compass needle. When an electric current flows through a conductor, it generates a magnetic field around it, which can interact with the magnetic field of the compass needle, causing it to deflect. This principle is the basis for electromagnetism.
No, a compass needle is not a transformer. A compass needle is a simple magnetic instrument that aligns itself with the Earth's magnetic field to show the direction of North. Transformers, on the other hand, are devices used to change the voltage and current levels in electrical circuits.
LEDs are used in some compass testers to provide a visual indication when the compass needle is aligned with the Earth's magnetic field. When the needle points north, it completes an electrical circuit that activates the LED, serving as a simple and effective way to confirm correct calibration.

The needle of a compass must be free to rotate so that it can point to magnetic north. The magnetic field of the earth not only rotates the compass needle horizontally but also pulls one end down. If it pulls the needle down it can stop it from turning freely so on many compasses the needle is balanced for use in a specific zone. There are 5 zones. Austraila and Britain are in different zones. This means the needle may not be level if used in the other's zone. Needles are balanced by making one end of the needle longer or by adding weight to one end of the needle.

The characteristic of magnetism in the compass needle allows it to align itself with the Earth's magnetic field, indicating the North and South poles. This alignment enables the compass needle to point towards the magnetic North pole of the Earth when used with a magnet.
A lensatic compass is a compass with a magnifying glass on the sight which makes it easier to view the needle. These types of compasses are frequently used in the military.

When a compass is held close to a wire carrying a current, the magnetic field produced by the current will deflect the compass needle. This happens because a magnetic field is generated around the wire due to the flow of current, and the compass needle aligns itself with this magnetic field. The deflection of the compass needle can be used to determine the direction of the current in the wire.
