Contagious magic is a concept in folklore and anthropology that suggests that objects can transfer their magical properties to other objects or people through direct contact. For example, if a person possesses a powerful item, such as a charm or amulet, it is believed that touching or being near that item can impart its magical qualities to them. This type of magic is often contrasted with sympathetic magic, where the connection is based on similarity or representation rather than physical contact. Contagious magic is commonly found in various cultures and is often associated with rituals and practices aimed at harnessing the power of specific objects or materials.
