We calculated the change of the magnetic flux through the surface encircled by the Earth's orbit. This change is associated with the magnetic flux transfer by the solar wind flow and exhibits clear 22-year periodicity. The magnetic flux transferred by the solar wind is of the same order of magnitude as the flux of the main solar magnetic field through the northern hemisphere of the Sun. There seems to be a feedback between the solar wind and the solar magnetism.

Key words: Sun: activity – Sun: magnetic fields – Sun: solar wind
