Observational analysis reveals 0.4–0.6% vector anisotropy of galactic cosmic rays from solar wind, indicating electromagnetic effects.
We calculate the characteristics of the anisotropy of galactic cosmic rays formed by an electromagnetic mechanism. The mechanism is based on the combined action of the induction electric field and the regular magnetic field of the moving solar wind. For cosmic rays with an energy of 10 GeV, the following results were obtained: 1) vector anisotropy of 0.4 – 0.6% is directed perpendicular to the Earth-Sun line from west to east; 2) tensor anisotropy has the form of a biaxial ellipsoid, the minor axis of which is directed along the interplanetary magnetic field. The calculations correspond to the measurements.
