The magnetic force between two magnets decreases as the distance between them increases. This is an inverse square relationship, meaning that if you double the distance, the force becomes four times weaker.

Here's why:

* Magnetic Fields: Magnets create invisible magnetic fields around them.

* Field Strength: The strength of a magnetic field decreases with distance from the magnet.

* Interaction: The magnetic force between two magnets arises from the interaction of their magnetic fields.

In simpler terms, the further apart the magnets are, the weaker their influence on each other becomes.
