The Earth magnetic field is shielding the Earth from charged cosmic particles such that a relatively strong magnetic field reduces the production of radiogenic isotopes. The solar wind is a stream of charged particles emitted from the Sun, which varies with the solar activity. The Earth reacts to the solar wind by increasing the strength of the shielding magnetic field. Therefore, higher solar activity results in stringer shielding and thus lower production of cosmogenic isotopes. The combined magnetic field from the Earth itself and the reaction to the solar wind constitutes the Earth magnetosphere, illustrated by an artists' view below in blue.
