How do compasses work in the desert?

Compasses work in the desert in the same way they do elsewhere, by aligning a magnetic needle with the Earth's magnetic field. The needle, which is magnetized, will always point toward the magnetic north pole, allowing users to determine their orientation. However, in desert environments, factors like large metal objects or geological formations may affect compass accuracy, so it's important to account for potential magnetic interference. Additionally, the vast, open landscapes of deserts can make navigation more challenging, requiring careful attention to landmarks and terrain.
