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.

Are the magnetic field lines in the picture correct?

• Yes, because they point from north to south.

• No, because they point from north to south (they're supposed to go the other way).

• Yes, because the North pole is on the left in all pictures.

• No, because the North pole is on the left in all pictures (it's supposed to be on the right).
