Compass Magnetic

A magnetic compass is a navigational instrument that indicates direction by utilizing the Earth's magnetic field. It works by aligning a magnetized needle with the Earth's magnetic field, pointing towards magnetic north. This allows users to determine cardinal directions (North, South, East, West) and orient themselves on maps. They are also valuable tools in education, helping students understand magnetism and orientation.

A compass needle deflects when placed near a current-carrying wire because the electric current generates a magnetic field, which interacts with the compass's magnetic needle. This phenomenon demonstrates the relationship between electricity and magnetism, showcasing that moving electric charges produce a magnetic field.

When electric current flows through a wire, it creates a magnetic field around the wire. When a compass is placed near a current-carrying wire, the magnetic field produced by the wire exerts a force on the compass needle, causing it to deflect from its usual north-south direction. The direction of the deflection depends on the direction of the current flow and the position of the compass relative to the wire. The direction of the magnetic field around a current-carrying wire can be determined using the right-hand rule: if you point your thumb in the direction of the current, your fingers will curl in the direction of the magnetic field lines.
