You can use a magnetic compass to find directions. It uses Earth’s magnetic field:

It has a freely moving magnetic needle that always points in the North-South direction
The needle rests on a scale called the compass rose, marked with directions: N, E, S, W
The “N” on the needle points toward geographic north
The compass also has degree markings:

North = 0°
East = 90°
South = 180°
West = 270°
These angle markings help in navigation and measuring bearings
