How Does the Earth's Magnetic Field Actually Work?

The Earth has a giant invisible shield, like the way a fridge magnet holds up paperclips. Inside Earth, there’s a hot liquid metal called molten iron that moves around in a big swirl, kind of like a blender on high. This movement creates electricity, which turns into a magnetic field, and it helps protect us from space stuff.
