Iron pieces accelerate toward the magnet, and the energy stored in the system decreases.

Reason: ferromagnetic iron is attracted into regions of stronger magnetic field; moving the iron into the field lowers the magnetic-field energy (the lost field energy appears as kinetic energy of the pieces and heat if dissipated).
