How Do Generators Work?

The video explains how large industrial generators produce electricity by using the principle of electromagnetic induction, discovered by Michael Faraday in 1835. It describes how moving a coil of conductive metal within a magnetic field generates an electrical current. The video also covers factors affecting the induced current, such as speed, coil loops, and magnetic field strength. It highlights the power sources for large generators, like wind and coal, and concludes with the importance of this technology in powering modern society.
