Removing the balls doesn't change the polarity of the tips of course, but it does change the direction of the entrained neutrals, due to more +ve ions moving from the rotor tips towards the stator tips than there are -ve ions moving from the stator tips towards the rotor tips. Only the -ve ion flow is present with the balls on.(*)
