How does magnetic north differ from true north?

Magnetic north refers to the direction a magnetic compass points, which is influenced by the Earth's magnetic field. This is not a fixed point, as it can shift over time due to changes in the Earth's magnetic field. True north, on the other hand, refers to the direction toward the geographic North Pole, which is a fixed point on the Earth's surface.

Understanding the distinction between magnetic north and true north is crucial for navigation. Pilots and navigators need to be aware that their compass may not always align perfectly with true north due to magnetic variation, which can differ based on geographic location. This is why charts and navigational systems often provide information to help convert between magnetic headings and true headings, ensuring accurate navigation.

In contrast, while some may think of magnetic north as being determined by satellites, it is primarily a product of the Earth's magnetic properties, and true north remains constant based on geography. Additionally, magnetic north is not a fixed location; it shifts due to changes in the Earth's magnetic field. Finally, magnetic and true north do not point in the same direction universally; they can differ significantly depending on where you are on Earth.
