How do magnets attract or repel each other without touching?

Magnets can pull or push each other even when they’re not touching, like how your favorite toy car can move without you pushing it.

Imagine two magnets are like two kids with invisible strings attached to their hands. If both kids pull the string toward them, they’ll move away from each other, that’s repelling. But if one kid pulls and the other lets go, the first kid will zoom toward the second, that’s attracting.

Now think of a magnet as having two invisible helpers: one on each end. One helper is like a friendly person who likes to say “hi” and pull others close, we call this a north pole. The other helper is someone who says “go away!” and pushes people off, that’s the south pole.

If a north pole meets another north pole, they both say “go away!” and push each other apart. But if a north pole meets a south pole, they say “hi” and pull toward each other.

So even when magnets aren’t touching, their invisible helpers are working hard to either pull or push, just like the kids with the invisible strings! Magnets can pull or push each other even when they’re not touching, like how your favorite toy car can move without you pushing it.
