MagneticDeclination

Magnetic declination is the angle between true north (geographic north) and magnetic north (the direction a magnetic compass points). Since magnetic north shifts over time due to changes in Earth's magnetic field, declination varies by location and can be east or west. Knowing the declination helps accurately navigate by adjusting compass readings to match true directions, ensuring your navigation aligns with maps and geographic coordinates. It’s an important factor for precise navigation, especially in outdoor activities like hiking or maritime travel.
