Is the purple magnet moved with or against the magnetic force?
with the magnetic force
against the magnetic force
When the purple magnet is moved against the magnetic force, what happens to the potential energy in the system?
it increases
it decreases
it stays the same

the magnets will move towards each other
the magnets will move away from each other
they will not move
What causes them to move away from each other?
the magnetic field
the magnetic force
the magnetic pole
the magnetic field lines
