【Why does a compass point north?】 A compass has a small needle. The needle is a magnet. A magnet has two ends: N (north) and S (south). The Earth is like a big magnet. The north part of the Earth is actually a south pole. N and S pull each other. So, the N side of the needle is pulled to the north. That is why a compass points north.
