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.

A child sets identical magnetic carts on tracks. At the end of each track is a large magnetic train that cannot move. The child uses her hand to slide the carts on each track. Which of these movements will result in the greatest increase in potential energy?

• Moving the cart on Track A one space to the left   <

• Moving the cart on Track B one space to the left <

• Moving the cart on Track B one space to the right >

• These movements each have the same change in potential energy because they each move the car the same distance.

A child moves a blue magnet towards the red magnet that cannot move. What happens to the potential energy in the system of magnets?

• Potential energy decreases because the blue magnet train moves in the same direction as the magnetic force.

• Potential energy decreases because the blue magnet train moves against the magnetic force.

• Potential energy increases because the blue magnet train moves against a magnetic force.

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

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 energy can convert potential energy stored in a gravitational field to kinetic energy.

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