Geomagnetism is the study of the Earth's magnetic field and its effects. The Earth has a magnetic field that is generated by the movement of molten iron in its outer core. This magnetic field helps to protect the Earth from harmful solar radiation and plays a crucial role in navigation for many animals, such as birds and sea turtles, that use it as a compass to navigate during migration. Some research suggests that geomagnetism may also play a role in the behavior of other animals, such as bees and even some mammals. Overall, geomagnetism is a fascinating field of study that highlights the intricate ways in which the Earth's magnetic field influences various aspects of life on our planet.
