Here's why:

* Magnetic fields: Magnets create invisible areas of influence called magnetic fields.

* Like poles repel: When two magnets have the same poles facing each other (e.g., both north poles), their magnetic fields interact in a way that causes them to push away from each other. This happens even if the magnets aren't physically touching.

Example: Think about two bar magnets with their north poles facing each other. You'll observe them pushing away, demonstrating that magnetic forces can repel without physical contact.
