Geomagnetism

Geomagnetism refers to the study of the Earth's magnetic field, which encompasses the properties, variations, and sources of the magnetism within and around our planet. This includes the analysis of the Earth's internal magnetic field generated by movements within its molten outer core, as well as its interaction with solar wind and cosmic radiation. Geomagnetism is important for understanding various geological and atmospheric phenomena, navigation, and the behavior of charged particles in space. The Earth's magnetic field influences technologies such as compasses, satellite systems, and communication networks. Additionally, geomagnetism has implications for geophysical research, including studies of plate tectonics, climate change, and the history of the Earth's magnetic field over geological time.
