Hypnotic means so rhythmic and absorbing that it puts you into a kind of trance. You meant to look away five minutes ago.
It describes rhythm, movement and voices, so a hypnotic beat, hypnotic waves and a hypnotic speaker all hold attention without effort. It is a compliment about art and a warning about screens. The clinical sense is precise, since a hypnotic drug is one that induces sleep. Hypnosis itself is a genuine and poorly understood state, and stage hypnotism has given the whole field a doubtful reputation.

Hypnotic means sleep-bringing. Greek hypnos was sleep and hypnōtikos meant inclined to put to sleep, so a hypnotic rhythm is one that puts you under.
