According to National Geographic, for a planet to generate its own magnetic … WebOct 27, 2024 · Earth's magnetic field is important because it protects the Earth against harmful radiations, such as solar winds, which contain harmful levels of radiation. Earth's magnetic field deflects most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds. Calculations … See more Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the See more Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind.
