The Earth has a magnetic field because of something moving deep inside it, like a giant magnet! Imagine the Earth is like a spinning bowl full of liquid metal. As it spins, this metal moves around and creates a magnetic field that helps compasses point north. It’s like having a secret power from way down below.
Examples
- A compass needle points north because of the Earth's magnetic field, like it’s being pulled by an invisible magnet.
- If you have a spinning bowl full of water, the movement creates currents, just like how Earth’s core works.
- Imagine a giant battery inside the Earth that constantly switches on and off to keep your compass working.
