'Die Zauberei' (magic) belongs to the word family of 'der Zauber' (magic, spell) and the verb 'zaubern' (to do magic). The ending '-ei' here refers to the activity or art of doing magic.
Er glaubt nicht an Zauber, aber er liebt Geschichten über Zauberei.
He doesn't believe in magic, but he loves stories about sorcery.
When 'Zauberei' (magic) is used without an article or in the singular as an uncountable noun, it means the art of magic or something inexplicable. If someone speaks of 'einer Zauberei' (a magic trick) in a countable sense, they mean a single trick.

The colloquial expression 'Das ist keine Zauberei!' (It's not magic!) is often used to say that something is not nearly as complicated as it may look.
Ein einfaches Nudelgericht zu kochen, ist wirklich keine Zauberei.
Cooking a simple pasta dish really isn't magic.
miracle / wonder
'das Wunder' and 'die Zauberei' can both have to do with something amazing or inexplicable. 'Wunder' more often means a special event or result that you can hardly explain and that often feels very positive. 'Zauberei' more often means magic, magic tricks, or something that looks like magic. You can confuse the words when something works surprisingly well. In everyday language, people sometimes say 'Das ist ja Zauberei' (That's like magic), but 'Wunder' puts stronger emphasis on the amazing event itself.
