How Could Magnetism Explain The Formation Of The Earth
Scientists from the University of Leeds and the University of Chicago have now looked at fluid dynamics and electrically conducting fluids. They conclude that the Earth must have become magnetized either before or as a result of the collision. They claim this could help constrain theories of Earth-Moon formation and inform future research into what happened. This updated assessment is based on the resiliency of Earth’s magnetic field, which is maintained by a geodynamic, a rotating fluid that carries electricity to the outer core....
