Magnetic Declination Add-on

The magnetic field of our planet plays an important role in phenomena as diverse as the Aurora Borealis and the migration of birds and marine animals. It shields the surface from hazardous extraterrestrial radiation and has been a crucial tool in navigation.

The Magnetic Declination Add-on portrays a number of properties of Earth's magnetic field. These parameters include declination, inclination and field strength. Isogonic contours and intensity maps provide a picture of how the magnetic field varies across the face of the globe.
