Earth molten core magnetic field
WebDec 22, 2016 · The inner solid core reaches from 5,100 km to the center of Earth. The Earth’s magnetic field is mainly created by a giant dynamo in the molten outer core. The magnetic field shields us from damaging radiation from Space and it impacts on navigation systems on Earth. It’s forever changing and hence important to study. WebJul 8, 2024 · The Earth’s core is magnetic because it has a molten outer core that is in constant motion. The motion of the molten outer core produces an electric current which then produces a magnetic field. Iron loses its magnetism when it’s heated to a few hundred degrees, yet Earth’s core – which produces a strong enough magnetic field to hold ...
