Welcome to SoM and Wicca! To define Magick, would be.. Releasing a energy from your body, into the universe, and that certain energy sort of "makes" or manifests into your desire or spell. It can be a bit confusing. Do some research on Wicca and different types of Wicca so you can find the right one for yourself. Look into making a Book Of Shadows (journal) to keep spells, rituals, candle color meanings, aura color meanings and more. I recommend before starting spells try meditation and do more research. I still research and I'm practising a Year! I think a Witch is always open to getting more knowledge.
Blessed Be ~
