Magick is another word for transformation, creation, and manifestation. Wicca magick is a tool we use to act on the subtle - or energy, or quantum - level of reality. The quantum level is the causal realm. It is the subtle influences at the quantum level that decide which way reality will go. So if you want to manifest something into ordinary reality, you start by stimulating the quantum realm to favour that potentiality. That is real magick in action. Science has known since early in the last century that the material world is made up not of matter, but of energy. And while matter is fairly stable, energy is very fluid. So it is difficult to build a house or job or lover with your bare hands if the causal realm hasn't already foreseen these things, but it is much easier to create an energy wave that will lead to a house or job or lover coming to you. (Of course, you still will need to use your body to manifest them.) That's what real magick is all about. In magick we transform our reality, and ourselves, to match our choices. And of course, Wicca Magick is a key component to the wiccan religion.
Working magick is what witch craft is all about. What would Wicca be without Magick? In fact, the standard explanation for the origins of the words witch and Wicca is that they are derived from "wic," which means to shape or bend. (As in wicker furniture.) While anything claiming to be historical is doubtful, the fact that we explain the word this way tells us a lot about Wicca - that its essence is transformation. Magick is at the heart of Wicca.
