Here's a breakdown:
* True North: This is the geographic North Pole, the point where all lines of longitude converge.
* Magnetic North: This is the point where Earth's magnetic field lines converge. It's not fixed like the true North Pole and shifts over time.
Why is there a difference?
Earth's magnetic field is generated by the movement of molten iron in the Earth's core. This magnetic field is not perfectly aligned with the Earth's rotational axis, leading to a difference between true north and magnetic north.
How to find declination:
* Online tools: Websites like NOAA's National Geodetic Survey provide magnetic declination calculators where you can enter your location.
* Compass: Some compasses have built-in declination adjustment mechanisms.
* Maps: Some maps include declination information.
Important note: Magnetic declination is a crucial factor in navigation, especially for long distances or when using compasses. Ignoring declination can lead to significant errors in direction and location.
