Almost all of the wow mage spells you'll be getting until you hit +60 but you can get five wow mage spells from levels 21-30. Their practical use to you relies on what spec you pick playing. At level 22, you gain Ice Lance. This is a low-mana instant cast frost spell, which means you can cast it on the move. This spell becomes much more powerful/useful for frost mages at level 24, when all mages gain another set of speciality-based spells or effects. This is also the point where you gain enough wow mage spells to begin rotation for every spec,and you're also gaining gold for your First Mount

So, you are getting the hang of being a mage. Now comes zones noted for punishing instances and grueling quests, really you'll find better part of WoW since you can start in your upper 20's in wetlands and work most of azeroth from 25-45 but for the time being 30 - 40 is where were at.
