Ramon put two magnetic toy trains very close to each other on a track. What will happen next and why?

• The trains will move closer to each other because the magnetic force will pull the trains together.

• The trains will not move because the magnets are not touching.

• The trains will move away from each because the magnetic force will push the trains apart.
