How can magnets cause objects to have kinetic energy?

• A magnetic force can convert kinetic energy stored in a magnetic field to potential energy.

• Kinetic energy can convert potential energy stored in a gravitational field.

• A magnetic force can convert potential energy stored in a magnetic field to kinetic energy.

How does a system of magnets store potential energy in the magnetic field?

• The energy used to move a magnet with (same direction as) a magnetic force.

• The energy used to move a magnet against (opposite direction as) a magnetic force.

• Magnets get their potential energy from kinetic energy.

In a computer simulation, Jeffrey moves a magnet (Magnet 2) toward another magnet (Magnet 1) that cannot move. What happens to the potential energy in the system of magnets?

• The potential energy does not change because the magnets in the system do not change.

• The potential energy increases because Magnet 2 moves against the magnetic force.

• The potential energy decreases because Magnet 2 moves against the magnetic force.

• The potential energy decreases because Magnet 2 moves in the same direction as the magnetic force.

Abdul moves a magnetic toy train away from a magnet that cannot move. What happens to the potential energy in the system of magnets during the movement?

• The potential energy decreases because the train moves in the same direction as the magnetic force.

• The potential energy decreases because the train moves against the magnetic force.

• The potential energy increases because the train moves against the magnetic force.

• The potential energy does not change because the magnets in the system do not change.
