Well fist of all fit the number of point to the number off marks avalable, secondly say about how the current moves through the coil and this produces an electromagnetic field which is deflected by the magnets making the armature move and how the communtator then flips the dirrection of the current and therefore repeating the process that leads to movement. Hope it helps if a bit wordy!
