We explain the Faraday Disk (Disc) Dynamo, a famous example of electromagnetic (EM) induction. This is an example of a DC (direct current) generator, and often turns up in exam questions on EM (regenerative) braking in vehicles. We discuss the physics of the dynamo, touching on Faraday's law, Lenz's law and Fleming's left hand rule. Throughout, we pose some questions for you to try, to keep the video interactive (and to keep you on your toes!).
