How Does a Compass Work Without Electricity?

A compass works like a little magnet that follows the Earth’s hidden magnet. Imagine the Earth is a giant bar magnet, and the compass needle is also a tiny one. The needle turns until it lines up with the Earth’s invisible magnetic field, and that means north! It doesn’t need electricity because magnets are always trying to match each other.
