While "magic" can be used as a noun referring to the practice or art of magic, it's also the abstract noun representing the concept of:
* The supernatural power or influence that is believed to be used to control events or influence people.
* The mysterious or inexplicable aspect of an event or situation.
For example:
* The magician performed acts of magic. (Here, "magic" refers to the art of magic.)
* The story was full of magic and wonder. (Here, "magic" refers to the abstract concept of supernatural power or mystery.)
