A compass uses a special needle that can spin freely. This needle is magic because it’s made of iron, which likes to follow the Earth's hidden magnetic lines. When you hold a compass, the needle turns so it points north, like a little magnet following an invisible road!
Examples
- A little compass in your backpack helps you find your way through the woods.
- The needle on a compass always points north, even if it’s not moving around!
- You follow the direction of a compass like it's giving you directions from an invisible friend.
