The raised center ring reduces friction against the bottom of the flask allowing the stir bar to spin faster and more easily, increasing the funneling effect. Having a proper funnel to the bottom of the flask helps aerate the wort and maximizes yeast growth.
While the stir plate we recommend comes with two magnetic stir bars (1.18" and 1.38", spares are always good as these are easy to lose. We find that various lengths from 1.18" to 2" work well with our recommended stir plate in both both 2L and 5L flasks, but these shorter 1.18" ones tends to be more stable (less chance of the stir bar getting thrown).
Hint: When you're done making a starter and want to get the stir bar out for a second starter or before you pitch, use a rare earth magnet on the outside of the flask to pull it up the side. While there's no harm in accidentally dumping the stir bar into the fermenter (we've all done it), you will inadvertently forget it's in there and end up pouring it down the drain when you go to clean the fermenter. That's why it's always good to have spares. ;)
