Although the dwemer have advanced technology, I think they also use magic. In their automatrons, they have Soul Gems to power them (or at least there are some in the bots) which suggests magic, since you have to fill the gems. In addition, In Mzulft, there's the contraption that requires magic to work, which suggests they definitely used magic to at least set it up. There's a lot of other evidence, but I'm drawing a blank right now unfortunately.
