Step 1
Step 2
Scientists are looking for new ways to produce electricity from renewable resources.
Answer
In the diagram, the floating ball can move due to wave motion, creating relative movement between the magnet inside the coil of wire and the coil itself. This movement generates electricity through electromagnetic induction, based on Faraday's law, which states that a change in magnetic field within a coil induces voltage. Therefore, utilizing the motion of ocean waves is an effective way to harness renewable energy.
