Mesmerism is a term used to describe the combination of MAGNETISM, hypnotism, and HYPNOSIS. It was developed by Franz Anton Mesmer in the 18th century and is based on the idea that an invisible natural force, or 'animal MAGNETISM, ' can be used to influence people's behavior. Mesmerism is often used in therapy to help people overcome mental and emotional issues. It is also used in entertainment, such as stage HYPNOSIS, to create a sense of awe and wonder.
