What generates Earth's primary protection, the magnetosphere, against solar wind?

Answer

The planet's molten iron core

Earth's defense against the harmful solar wind and the vast majority of charged particles streaming from the Sun is the magnetosphere. This structure functions as a protective magnetic bubble surrounding the planet. The generation of this powerful magnetic field is directly attributed to the dynamic movement within Earth's interior, specifically the circulation and movement within the molten iron core, which creates the necessary global magnetic field for deflection.
