Answer
The device in the diagram generates electricity from wave energy. The movement of the floating ball due to wave action causes the magnet inside the coil to move, inducing an electric current according to Faraday's law of electromagnetic induction. As the magnet moves, it creates a changing magnetic field within the coil, thereby generating electric energy that can be transferred to the shore via the steel cable.
