1 If the distance between two magnets is doubled the magnetic force between them will fall to a quarter of the initial value. #(F//4)#.  If the distance between two magnets is halved the magnetic force between them will increase to four times the initial value. #(4F)#.
If you bring two bar magnets together, there are two things that can happen: if you bring a north pole and a south pole together, they attract and the magnets may stick together. if you bring two north poles together, or two south poles together, they repel and the magnets push each other away. We say that unlike poles attract, and like poles repel.
