The outer liquid core produces the strong magnetic field of the Earth, through the dynamo effect.
The Outer Core
In the Dynamo Theory, the magnetic field of the earth is created in the outer core. The fluid contained in the outer core creates and maintains the magnetic field during rotation.

The earth's outer core produces the magnetic field.
What escapes the crust is what we observe as the earths magnetic field. The outer core is a rotating mass of fluid metal that induces an electrical current which in turn generates the magnetosphere.

The entire Earth spins. No layer has a rotation rate the differs significantly from the rest of the planet. If any layer did the results would be catastrophic. The magnetic field is the result of convection currents in the outer core.

The Ozone layer of the earth protects the earth from the harmful UV radiations of the sun.
