This question refers to the conversion of true north to magnetic north.
True north is a fixed point at the North Pole, representing the direction of the Earth's axis of rotation.
Magnetic north, on the other hand, is a point where the Earth's magnetic field lines converge. This point is not fixed and changes over time.
To convert true north to magnetic north, you need to determine the magnetic declination at your location.
Magnetic declination is the angle between true north and magnetic north. It can be either east or west.
Here's how to convert true north to magnetic north:
- Determine your location: Find your latitude and longitude coordinates.
- Find the magnetic declination: You can use online tools like the National Oceanic and Atmospheric Administration (NOAA) Magnetic Field Calculator to find the magnetic declination for your location.
- Apply the declination:
- If the magnetic declination is east, add the declination angle to your true bearing.
- If the magnetic declination is west, subtract the declination angle from your true bearing.
Example:
Let's say your true bearing is 0° (north) and the magnetic declination at your location is 10° east. To convert true north to magnetic north, you would add 10° to your true bearing, resulting in a magnetic bearing of 10°.
Important Note:
Magnetic declination varies depending on your location and time. It's essential to use the most up-to-date information for accurate conversions.
