Magnetic variation

Magnetic variation, also known as magnetic declination, refers to the angle difference between true north (geographic north) and magnetic north (the direction a compass points). This variation occurs because the Earth's magnetic field is not perfectly aligned with its rotational axis. As a result, the direction of magnetic north can differ depending on where you are on the planet. Understanding magnetic variation is crucial for navigation, as it helps ensure accurate readings when using a compass, especially in certain regions where the difference can be significant.
