Explanation:

Attract is the action of moving an object or anything closer to another, take a magnet for example: it attracts metal.

Repel is the movement or act of moving an object of matter away from another. Take the same magnet for example. Magnets have a north and south side, or side A and B. Side A will attract and connect to side B, however, it will repel its matching side. That means side A will repel another magnet's side A, vise versa with side B, it will repel itself.
