The video explains how a compass works by aligning its magnetic needle with Earth's magnetic poles. It describes the compass's components: a magnetic needle, a pivot, and a marked disc. The Earth's magnetic field, strongest at its poles, attracts the compass needle, allowing it to point north. This helps users determine directions on Earth.
