Does the magnetometer provide accurate measurements in any geographical location?

Last Updated: Jul 26, 2016 05:55PM CDT

Magnetic north and true north vary by location, but in a predictable way. The magnetometer’s measurements could also be affected by the soft and hard iron effects. These distortions are generated through materials that interfere with the Earth’s natural magnetic fields. These include but are not limited to nickel, iron, and magnetic materials.
