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)#.
The north pole is normally shown as N and the south pole as S. Magnets are made from magnetic materials. These are metals that can be magnetised or will be attracted to a magnet. Most materials are not magnetic, but iron, cobalt and nickel are magnetic. Steel is mostly iron, so steel is magnetic too. Attract and repel. If you bring two bar magnets together, there are two things that can happen: 1  if you bring a north pole and a south pole together, they attract and the magnets may stick together. 2  if you bring two north poles together, or two south poles together, they repel and the magnets push each other away.
