The movement of cosmic ray particles across space, such as electrons and protons, is influenced by the sun's magnetic field, causing fluctuations in the intensity of galactic cosmic rays (GCRs) reaching Earth in response to the solar cycle. During periods of low solar activity, such as the solar minimum, more GCRs have been observed to reach Earth compared to that for periods of high solar activity. This inverse correlation between the GCR-flux and solar activity is known as "solar modulation."
