This solar wind carries the magnetic field of the star and constitutes a fluid that has an electromagnetic interplay with flow obstacles, such as planetary magnetic fields. The regular conditions in the solar wind flow are drastically disturbed by transients that originate from huge eruptions of plasma and magnetic flux in the Sun. In interplanetary space, these eruptions are known as interplanetary ... VO - IS - SP - OP - KW - fysiikka N1 - PP - ER -
