2. When two powerful, attracting magnets are held apart and then released, what happens to their stored energy? A:
3. What happens when two repelling magnets are held apart? A:
4. Give an example of how the energy stored in a magnetic field can be used in the real world. A:

one sentence each

Answer 1

1. A: Opposite poles (north and south) attract while like poles repel.
2. A: The magnetic potential energy converts into kinetic energy as they accelerate together and then into heat, sound and slight deformation when they collide and stick.
3. A: If released, the stored magnetic potential energy converts into kinetic energy as they accelerate apart and then into heat and sound when their motion is stopped.
4. A: In an electric motor, energy stored in magnetic fields is converted into mechanical work to turn a shaft (e.g., in household appliances and electric vehicles).
