Two donut-shaped magnets are stacked on top of each other with a
wooden dowel in the center. The south poles of the magnets are
facing each other. Once the upper magnet is released, it accelerates
downward and stops 1 cm above the lower magnet. How does the
energy stored in the magnetic field change? (1 point)
All of the energy stored is converted into kinetic,
thermal, and gravitational energy.
All of the energy stored is converted into kinetic and
thermal energy.
Some of the energy stored is converted into kinetic
and thermal energy.

When the upper magnet is released and accelerates downward towards the lower magnet, some of the energy stored in the magnetic field is converted into kinetic energy (the motion of the magnet) and thermal energy (due to friction and air resistance). Gravitational potential energy is also involved in this scenario, but it is not directly related to the energy stored in the magnetic field.
