Here's why:
* Inverse Square Law: The strength of a magnetic field decreases rapidly with distance. This is known as the inverse square law. The farther away the magnet and paper clip are, the weaker the magnetic force becomes.
* Magnetic Field Lines: Magnetic fields are represented by lines of force that emanate from the poles of a magnet. These lines are denser closer to the magnet. When the paper clip is close to the magnet, it experiences a greater concentration of magnetic field lines, leading to a stronger attraction.
In simpler terms: Think of it like gravity. The closer you are to the Earth, the stronger its gravitational pull on you. The same principle applies to magnets and magnetic objects.
