.Scott said:Birkeland currents don't only go between the Sun and the Earth, they go between the Sun and Saturn, and the Sun and Uranus, and Neptune......
Hannes Alfven:
Alfven said:The correlation of the magnetic storms and aurorae with the solar activity indicates that they are due to some agent emitted from the sun. As this agent causes magnetic and electric disturbances on the earth, it probably consists of charged particles. But, as Schuster has shown, the emission of a sufficient amount of particles, all having the same sign, is impossible because it would give rise to an enormous space charge. This difficulty is avoided if the emitted agent is assumed to consist of the equal amount of positive and negative particles.
Consequently the general nature of the current system during the main phase of a magnetic storm must be somewhat as follows. The stream approaching the earth contains positive and negative charge in equal amounts so that the electric current is zero.
Through the action of the magnetic field of the earth the paths of the positives and of the negatives become differentiated, but until the particles reach the forbidden region, the space charge is always zero because the positives and negatives neutralize each other.
