What are magnetic compasses?

A magnetic compass is a tool that helps you find directions using Earth’s hidden power, like having a friend who always knows which way to go.

Imagine you have a little toy boat floating in a puddle, and no matter how you push it, it always turns so its nose points toward the same direction. That’s kind of what happens inside a magnetic compass! It has a small, free-moving piece, like a tiny spinning top, called a needle, which is made of magnet stuff.

The Earth acts like a giant magnet, and it has north and south poles. The compass needle wants to line up with the Earth’s hidden magnetic power. When you look at a compass, the needle points toward north, just like your toy boat always turns in one direction.

If you’re on a walk or playing hide-and-seek and get lost, you can use a magnetic compass to find your way back, it’s like having a map that moves with you! No need for magic, just a little science and a needle that likes to point.
