How do compasses find magnetic north?
TechnologyNavigation
Quick Answer
A compass needle aligns with Earth’s magnetic field, so its north-seeking end points toward magnetic north. Magnetic north is not the same as geographic North Pole and slowly moves over time.
The Full Story
A compass contains a small magnetized needle that can rotate freely. Earth acts like a giant magnet, creating a magnetic field that guides the needle along field lines. The end marked north points toward magnetic north, which is currently located in the Arctic and has been drifting for years. Because magnetic north and true north are different, maps often include magnetic declination to correct for the difference.
