How does the outer core affect earth?

The twisting force created by this electromagnetic interaction may be what propels the rotation of the inner core. The circulating magma in the molten outer core generates a weak magnetic field, which the researchers suspect may be leaking into the inner core and generating an electric current.

According to Song, there could be consequences for satellites, rockets, and spacecraft if the Earth's inner core rotates differently. This is supported by this study: https://tutor.hix.ai

The magnetic field is 50 times stronger in the outer core than it is on the surface, and scientists believe the solid inner core stabilizes the magnetic field produced in the outer core. The liquid outer core is thought to create Earth's magnetic field through convection currents and the Coriolis effect. https://tutor.hix.ai

The magnetic field of the Earth is produced by the motion of molten iron and nickel in the outer core of the planet.
