Detailed explanation-1: -Geomagnetism deals with all aspects of the Earth’s magnetic field, also called the geomagnetic field, that surrounds our habitat in the form of the magnetosphere.
Detailed explanation-2: -The geomagnetic field is used to explore the dynamics of Earth’s interior and its surrounding space environment, and geomagnetic data are used for geophysical mapping, mineral exploration, risk mitigation, and other practical applications.
Detailed explanation-3: -remanent magnetism, also called Paleomagnetism, or Palaeomagnetism, the permanent magnetism in rocks, resulting from the orientation of the Earth’s magnetic field at the time of rock formation in a past geological age.
Detailed explanation-4: -Further Understanding of Geomagnetism The Earth’s magnetic field is described by seven parameters. These are declination (D), inclination (I), horizontal intensity (H), vertical intensity (Z), total intensity (F) and the north (X) and east (Y) components of the horizontal intensity.
Detailed explanation-5: -The Earth’s magnetic field is created by the Earth’s core. Movement within the core between the solid and liquid parts of the core create convection currents. There are several metals within the core, but iron creates electrical currents as it moves. This generates the magnetic field.
