Deep Inside Earth, Two Giant Hidden Structures May Be Steering the Planet’s Magnetic Field

Two massive structures deep within Earth, known as LLSVPs, are significantly influencing the planet\'s magnetic field. These hotter regions at the core-mantle boundary impede heat flow, altering the circulation of molten iron in the outer core. This uneven heat extraction shapes the geodynamo, impacting the magnetic field\'s generation and long-term behavior for millions of years.
