What process is responsible for generating a planet's protective magnetic field?

Answer

The dynamo effect, driven by a large, rotating, molten metallic core.

The magnetic field, which shields the atmosphere from being stripped by the solar wind, is generated by the dynamo effect, requiring a sufficiently large planet with enough internal heat to maintain a rotating, molten metallic core that facilitates convection.
