A magnet is slowly moved further away from a steel paperclip. What happens to the force on the paperclip, and why?
It decreases, because the magnetic field is weaker further away
It increases, because the magnetic field spreads out further away
It stays the same, because the strength of the magnet is unchanged
It decreases, because the paperclip becomes a permanent magnet
