Earth's magnetic field diagram
WebApr 1, 2024 · magnetic field, a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to line up in the direction of the field. WebThis is one of five world charts showing the declination, inclination, horizontal intensity, vertical component, and total intensity of the Earth’s magnetic field at mean sea level at the beginning of 2005. The charts are based on the International Geomagnetic Reference Field (IGRF) main model for 2005 and secular change model for 2005-2010.

Earth’s Magnetic Field Model There are different models to describe the Earth’s magnetic field. The Earth’s magnetic field can be described as a dipole model, a tilted-dipole model [3], and the International Geomagnetic Reference Field Model (IGRF) [4]. For a spacecraft in a circular orbit, the dipole model is commonly used to determine
