A giant magnet moves above a debris pile with many pieces of iron buried in it. Which statement is correct about the energy stored in the magnetic field? (1 point)

Question

Responses

Iron pieces accelerate away from the magnet, and the energy stored in the system increases.

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

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

Answer 1

The correct statement is:

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

When a giant magnet moves above a pile of debris containing iron pieces, the magnetic field exerts a force on the iron objects, causing them to accelerate towards the magnet. As they move into the magnetic field, the energy associated with the magnetic field and the kinetic energy of the iron pieces increases.
