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. [4] One stripping mechanism is for gas to be caught in bubbles of the magnetic field, which are ripped off by solar winds. [ 5 ]
English: Plot of the earth's magnetic field components, in the approximation of an ideal dipole field. The three plot lines show the total field strength (blue), radial (vertical) field component (magenta) and the horizontal (south to north) field component (yellow).
