A magnet is rotated inside a coil of wire, and the coil is connected to a light bulb. As the magnet spins, the changing magnetic field inside the coil induces an electromotive force (EMF), generating an electric current according to Faraday's Law of Induction. The alternating magnetic field, produced by the spinning magnet, continuously changes the magnetic flux through the coil, which in turn creates a varying current. This current powers the light bulb, causing it to illuminate. The faster the magnet spins, the greater the rate of change in magnetic flux, which results in a stronger induced current and brighter light. This setup illustrates the principle of electromagnetic induction and its practical application in generating electricity.
