How is the induced magnetosphere on Venus fundamentally created when the solar wind interacts with the planet?
When the stream of charged particles flowing from the Sun collides with the planet's upper atmosphere and ionosphere.
The induced magnetosphere is an external phenomenon contingent upon the presence of the solar wind. When the torrent of charged particles emanating from the Sun encounters Venus, the collision happens at the very edge of the planet's electrical boundaries—specifically the upper atmosphere and the ionosphere. This impact generates significant pressure on the plasma environment surrounding Venus. The result of this direct physical pressure is the compression and shaping of this external plasma layer into a magnetic barrier that bows around the planet, effectively shielding the bulk of the atmosphere from direct bombardment by the solar wind.
