Question

a magnetic launcher system stores potential energy before releasing a spacecraft model. which statement best explains how the system gained this stored energy?
the magnets created energy when they were pushed together
the system absorbed energy from the magnetic field automatically
energy entered the system when a force moved the objects into a new position
energy transferred into the system because a force compressed the magnetic field

Explanation:

Energy cannot be created, so the first option is invalid. Magnetic fields do not automatically transfer energy to the system. Compressing a magnetic field is not the correct framing here; instead, work (force moving objects) transfers energy to the system, storing it as potential energy. When a force moves the magnetic objects into a position where their magnetic fields interact to create stored potential energy, energy enters the system via that work.

Answer:

Energy entered the system when a force moved the objects into a new position
