Get two magnets . Fix one to a solid point. Stick them together N and S poles. Pull them apart . Then slowly move them back together . At a certain point you will feel the magnetic force pulling the unfixed magnet towards the fixed one. And at a certain point the magnetic force will not effect the unfixed magnet . Different size fixed magnets and unfixed magnets will have a different effect on each other . Just like different sized planets. Big fixed magnet(earth) tiny small iddy biddy magnet(rocket)
