What is a property of magnetism?

The correct answer highlights a fundamental principle of magnetism: opposite magnetic poles attract each other. This property is essential in understanding how magnets interact with each other. Each magnet has two poles—north and south—and it is widely recognized that when the north pole of one magnet approaches the south pole of another, they will pull towards each other, creating a force of attraction.

This phenomenon is a key concept in magnetism and has practical applications in various fields, including technology and engineering, where magnetic forces are utilized to create motors, generators, and other devices.

The other options do not accurately describe the behavior of magnets; some suggest incorrect interactions between poles. Understanding how opposite poles attract is crucial for grasping the basics of magnetism and its applications.
