Magnets can do this because they are surrounded by a magnetic field. It is the magnetic field that creates the force (a push or a pull) on other magnets or magnetic materials in the field. The magnetic field gets weaker as you get farther and farther away from a magnet so magnets can be very strong up close, but they do not have much of an
