In the books he cast produce flame(hobbit), lightning bolt(hobbit), knock(lotr), Light(lotr), fireball(lotr), counterspell(lotr), detect thoughts(lotr), and break enchantment(lotr). Perhaps more.Magic (and Galadriel). Magic is very understated in Tolkien's stories, so it is hard to say how it is used beyond relatively minor effects done by Gandalf. For instance, he used a sword in his battle against the Balrog, and so you can say that Gandalf was "magic-infused," but not casting D&D-esque spells.
