Here's why:
* Magnetic Force: Magnetism is a fundamental force of nature that arises from the movement of electric charges. Magnets create a magnetic field around them, which can attract or repel other magnetic materials like iron.
* Distance: The strength of the magnetic force decreases with distance, but it can still act over a considerable range.
* Iron: Iron is a ferromagnetic material, meaning it is strongly attracted to magnets.
