What happens when two unlike poles of magnets are brought together?

When two unlike poles of magnets are brought together, they attract each other. This attraction occurs because of the fundamental principle of magnetism: opposite poles attract while like poles repel. In the context of magnets, "unlike poles" refers to one magnet's north pole and the other magnet's south pole.

When these opposite poles align, they create a magnetic field that draws the two magnets toward one another. This property is essential in various applications, such as in electric motors and magnetic switches, where the attraction between opposite poles allows for efficient operation.

The other choices do not accurately describe the interaction between unlike poles. Repelling occurs when two similar poles are brought together. The idea of rotation might suggest movement due to magnetic forces but does not describe a specific interaction that occurs between unlike poles. Lastly, the term collision does not convey the nature of the magnetic interaction, which is characterized by attraction rather than a physical collision.
