A controversial new theory suggests that long-term changes in Earth’s main magnetic field are possibly induced by the oceans’ circulation.

Some 400 years of discussion and we’re still not sure what creates the Earth’s magnetic field, and thus the magnetosphere, despite the importance of the latter as the only buffer between us and deadly solar wind of charged particles (made up of electrons and protons). New research raises question marks about the forces behind the magnetic field and the structure of Earth itself.
