The best statement that describes the energy stored in the junkyard when a large magnet moves over it is:
**"Iron pieces will accelerate toward the magnet and increase the energy stored in the system."**
As the magnet approaches, the pieces of iron are attracted to it, which increases the kinetic energy of the iron pieces as they move toward the magnet. This results in an increase in the overall energy of the system as the magnet's magnetic field interacts with the iron pieces.
