Cuphook is a period-3 induction coil which contains one of only three period-3 three-cell rotors. The others are 1-2-3 and stillater. Like the candlefrobra, there are many possible stabilizations of the cuphook, many small examples of which arise naturally.

Many other natural oscillators exist with the same rotor as the cuphook, but with a different stator. The smallest example is open cuphook.
