How Does Earth and Compasses | Magnetism | Physics | FuseSchool Work?

Earth is like a giant magnet, and compasses are like little helpers that point north because of it.

Imagine Earth has an invisible bar magnet inside it, kind of like a toy magnet you might have at home. This hidden magnet makes the ground around us act like a magnet too, and it points mostly toward north.

Now think about a compass. It has a little needle that can spin freely. That needle is also a tiny magnet, and it wants to line up with Earth’s big invisible magnet. So when you look at a compass, the needle always turns so it faces north, like a friendly friend who knows where north is.

If you bring another magnet close to the compass, it might make the needle wiggle or point somewhere else, just like if you brought a new toy near your friend and distracted them!

So Earth’s magnet helps compasses work, making them really useful for finding directions. No magic, just magnets working together!
