How did Michael Faraday’s experiments lead to the development of electric generators?

Michael Faraday’s development of the electric generator was rooted in his 1831 discovery of electromagnetic induction. Through his experiments, Faraday observed that moving a permanent magnet in and out of a coil of wire induced an electric current within that wire.12

He conceptualized these magnetic effects as "lines of force" and determined that the magnitude of the induced current depended on the number of these lines cut by a conductor over time. Building on this principle, Faraday constructed the first dynamo—the direct ancestor of the modern electric generator—by rotating a copper disk between the poles of a powerful magnet. By connecting leads to the rim and center of the disk, he successfully produced a continuous electric current. This breakthrough demonstrated that mechanical energy could be converted into electrical energy, establishing the fundamental technology for power generation.13
